In the name of God, the Most Gracious, the Most Merciful, and peace and blessings be upon the most honorable of messengers O God, teach us what is beneficial for us, benefit us with what you have taught us, and increase our knowledge, O Generous One. And then.... I am Dr. Saad Abdel Rahman from Egypt. I am honored to help all medical college students in the Arab world in understanding medical subjects. Whether you are a human medicine, nursing, health sciences, medical diplomas, pharmacy or dentistry Even if you are still in the preparatory years Whether it is academic subjects such as physiology, pathology, bio, microbiology, pharmacology, and anatomy. Or clinical subjects such as internal medicine, surgery, forensic medicine, toxicology, obstetrics and gynecology, and ear, nose and throat. God willing, I will provide you with unconventional solutions for bio-pathology, microbiology, and anatomy. We will also understand physiology and pathology together. It will be a very enjoyable journey. We will do all of this and more together, and God willing, we will reach a high level of understanding and memorization that will enable us to reach the highest grades, God willing. With me, God willing, you will learn and study using the latest methods used globally, which I myself have benefited from, so prepare for the USMLE exams. New methods have impressed many students and have brought them more than wonderful results and solved their problems with subjects that were causing them complexes and major problems, specifically microbiology, pharma and bio. Our lectures will be live Zoom or recorded lectures, depending on what is best for you. Our lecture will be an explanation of your college’s files or files I prepared from the best and most modern sources in the world. I am waiting for you all and I am honored to meet you as soon as possible.

Biology is particularly a challenging subject because it requires you to first understand the enormous number of concepts and then memories it simultaneously. I'll teach biology through the slides I have prepared (ig/GCSE only) which are made from multiple resource, such as marking scheme, the book and examiner reports, this is beneficial as while I teach the concept it will come to the student the exact way the examiner wants the student to answer, and ofcource while learning the slides he will be Able to directly do the past papers as the notes are mastercopy of the source itself. Moreover, I'll make sure that each topic is fully understood by the student so there will be no room for error.

I have been a public school teacher for four years and have previously trained students to take the university entrance exams in this subject. Reinforcement classes will be given based on the official biology curriculum for the second year of high school in public education in Spain, with special emphasis on the relationship of concepts, deduction and a deep understanding of the subject in order to be able to face the entrance exam in optimal conditions and obtain a high average grade.

Cell Biology is a fundamental topic in both the IGCSE and CIE AS/A Level Biology curricula. It focuses on the structure, function, and processesof cells, the basic units of life. Here's a breakdown of the content at each level: --- IGCSE Biology (0610/0970) At the IGCSE level, cell biology introduces foundational concepts about cells, their structures, and processes: 1. Cell Structure and Organization -The Cell as the Basic Unit of Life: - Differences between plant and animal cells. - Identification and functions of cell structures (organelles): - Cell membrane: Controls the movement of substances. - Cytoplasm: Site of metabolic reactions. - Nucleus: Contains DNA and controls cell activities. - Mitochondria: Site of aerobic respiration. - Chloroplasts (plant cells): Site of photosynthesis. - Vacuole: Contains cell sap (large in plants). - Cell wall(plant cells): Provides structure and support. - Use of a light microscope to observe cells. 2. Specialization of Cells. - Specialized cells and their adaptations: - Red blood cells, nerve cells, root hair cells, ciliated cells, sperm cells, etc. - Understanding tissues, organs, and organ systems. 3. Movement of Substances - Processes for the movement of substances across membranes: - Diffusion: Movement of particles from high to low concentration. - Osmosis: Movement of water through a selectively permeable membrane. - Active transport: Movement of substances against a concentration gradient using energy. 4. Enzymes - Enzymes as biological catalysts and their role in cell processes. - Factors affecting enzyme activity: temperature, pH, substrate concentration. CIE AS and A Level Biology (9700) At the AS/A Level, cell biology expands significantly, focusing on advanced concepts, cellular processes, and microscopy: 1. Cell Structure - Prokaryotic vs. Eukaryotic Cells: - Prokaryotes (bacteria) lack a nucleus and membrane-bound organelles. - Eukaryotes (plants, animals, fungi, and protists) have a nucleus and organelles. - Structure and Function of Organelles: - Nucleus: Contains chromatin and nucleolus. - Mitochondria: Site of ATP production (aerobic respiration). - Ribosomes: Site of protein synthesis. - Endoplasmic Reticulum (ER): - Rough ER: Protein transport and modification. - Smooth ER: Lipid synthesis. - Golgi Apparatus: Modification, packaging, and transport of proteins. - Lysosomes: Contain enzymes for digestion. - Chloroplasts (plants): Site of photosynthesis. - Cell membrane: Phospholipid bilayer and fluid mosaic model. - Cell wall: Found in plants, fungi, and prokaryotes. - Microscopy: - Light microscopes and electron microscopes (TEM and SEM). - Calculations: magnification and actual size 2. Cell Membranes and Transport - Structure of the phospholipid bilayer (fluid mosaic model). - Functions of proteins in the membrane: carriers, channels, and receptors. - Transport mechanisms: - Diffusion, facilitated diffusion, osmosis, and active transport. - Endocytosis and exocytosis (bulk transport). 3. Cell Division - Mitosis: - Stages of mitosis: prophase, metaphase, anaphase, and telophase. - Importance of mitosis for growth, repair, and asexual reproduction. - Meiosis: -Production of gametes. - Significance in genetic variation through crossing over and independent assortment. 4. Cell Communication and Enzymes - Role of enzymes in metabolism (anabolic and catabolic reactions). - Cell signaling: How cells communicate via hormones and receptors. 5. Viruses - Virus structure and replication as non-cellular entities (e.g., HIV and influenza). - Summary - At the IGCSE level, cell biology focuses on basic cell structures, specialized cells, diffusion, osmosis, and enzyme functions. - At the AS/A Level, it covers advanced topics such as organelle structure, cell division, membrane transport, microscopy, and the differences between prokaryotic and eukaryotic cells.

Structure of the plasma membrane The plasma membrane is mainly composed of: Phospholipids: These amphipathic molecules (having both a hydrophilic and a hydrophobic part) are organized into a double lipid layer. This structure gives the membrane its semi-permeable barrier property. Proteins: They are integrated into the lipid bilayer and perform various functions: transport of molecules, reception of signals, cellular recognition, etc. Carbohydrates: Linked to lipids (glycolipids) or proteins (glycoproteins), they play an important role in cell recognition and cellular interactions. Function of the plasma membrane Selective barrier: The plasma membrane allows the selective passage of certain molecules while preventing others. Transport: Membrane proteins provide passive (simple or facilitated diffusion) or active (pumps) transport of molecules across the membrane. Receiving signals: Membrane receptors allow the cell to detect and respond to signals from its environment. Cell recognition: Molecules present on the surface of the membrane allow cells to recognize and interact with each other. Maintenance of homeostasis: The plasma membrane helps maintain a stable intracellular environment by regulating exchanges between the cell and its environment. Properties of the plasma membrane Fluidity: The plasma membrane is not a rigid structure but rather fluid, which allows it to deform and change shape. Asymmetry: The two faces of the plasma membrane have different compositions, which gives the membrane polarity. Plasma membrane models Fluid mosaic model: This model, the most accepted, describes the membrane as a constantly changing mosaic of lipids and proteins.

Biology can be tricky as it contains lots of different components. This can be introduced slowly as I will provide support over lessons teaching you lots of information but a slow and steady pace giving you questions and answers along the way. Homework will also be provided this is to ensure that the lesson has stuck into your head and you have grasped it. If not there is no worries as things can take a while to learn but by the end you will feel a lot less stress about what you may be learning in biology. You may be finding one specific topic in biology hard and we can always go over that in the lesson or we can find stuff to look over in the lessons to keep your brains up to date for upcoming important exams.
