Trusted teacher: In the CIE (Cambridge International) curriculum, Biochemistry is primarily covered in Biology and partially in Chemistry at both IGCSE and AS/A Level. It focuses on the chemical processes and molecules essential for life. Here's a detailed overview: IGCSE Biology (0610/0970) Biochemistry at the IGCSE level introduces students to basic biological molecules and processes: 1. Biological Molecules - Carbohydrates: - Monosaccharides (e.g., glucose), disaccharides (e.g., sucrose), and polysaccharides (e.g., starch, glycogen). - Role in energy storage and release. - Proteins: - Made up of amino acids. - Functions: enzymes, structural components (e.g., keratin), and hormones. - Lipids: - Fats and oils: composed of fatty acids and glycerol. - Role in energy storage, insulation, and cell membranes. 2. Enzymes - Biological catalysts that speed up reactions. - Factors affecting enzyme activity: temperature, pH, and substrate concentration. 3. Photosynthesis - Biochemical process in plants to produce glucose using light energy, carbon dioxide, and water. - Equation: 6CO2 + 6H2O → C6H12O6 + 6O2. 4. Respiration - Aerobic respiration: Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP). - Anaerobic respiration in humans: Glucose → Lactic acid + Energy. 5. DNA and Protein Synthesis (Basic level) - DNA as the molecule of inheritance. - Role of DNA in carrying genetic information. --- CIE AS and A Level Biology (9700) At the AS/A Level, biochemistry is studied in depth. Key areas include: 1. Biological Molecules - Carbohydrates: Structure and function of monosaccharides, disaccharides (e.g., maltose), and polysaccharides (e.g., starch, glycogen, cellulose). - Lipids: Triglycerides, phospholipids, and cholesterol. Role in membranes and energy storage. - Proteins: - Levels of structure: primary, secondary, tertiary, and quaternary. - Role of proteins in enzymes, antibodies, and transport (e.g., hemoglobin). - Nucleic Acids: - Structure of DNA and RNA. - Role of nucleic acids in protein synthesis. 2. Enzymes - Enzyme structure and mode of action (lock-and-key, induced fit). - Enzyme kinetics and factors affecting enzyme activity. - Competitive and non-competitive inhibitors. 3. Cellular Respiration - Glycolysis, Krebs cycle, and oxidative phosphorylation. - ATP production and its importance as an energy currency. 4. Photosynthesis - Light-dependent and light-independent (Calvin cycle) reactions. - Factors affecting photosynthesis. 5. Molecular Biology - DNA replication, transcription, and translation. - Role of mRNA, tRNA, and ribosomes in protein synthesis. 6. Biochemical Processes in Cells - Role of ATP in metabolism. - Metabolic pathways and enzyme regulation. --- CIE AS and A Level Chemistry (9701) While biochemistry is primarily a biology topic, it also features in chemistry at A Level: 1. Amino Acids and Proteins - Structure of amino acids and peptide bonds. - Protein hydrolysis and analysis. 2. Carbohydrates - Structure of glucose and its isomers. - Reactions of carbohydrates (e.g., oxidation). 3. Lipids - Structure of triglycerides, fatty acids, and phospholipids. - Saponification and ester formation. 4. Biochemical Techniques - Chromatography for separating amino acids and sugars. - Use of enzymes as biological catalysts in industrial processes. --- Summary - At the IGCSE level, biochemistry focuses on basic biomolecules (carbohydrates, proteins, lipids), enzymes, photosynthesis, and respiration. - At the AS/A Level, biochemistry delves deeper into molecular biology, enzyme kinetics, ATP production, protein synthesis, and metabolism.

£114MAKE A MARK ON THE MINDS OF RECRUITERS (impactful CV and cover letter)
Trusted teacher: Capturing the attention of recruiters and leaving a memorable impression on decision-makers is a subtle art. This is why I design for you, thanks to my experience as an HR expert, an impeccable CV and an impactful cover letter, perfectly in line with your aspirations. By entrusting me with the promotion of your journey, you will benefit from comprehensive support. The service that I offer, in French or English, is structured around four key assets: ▪ IN-DEPTH EXPERTISE I will first provide you with a detailed critical analysis report of your current CV/letter (identification of strengths and gaps). We will then carry out a 45-minute interview to understand your journey and your objectives in detail. ▪ A CAPACITY FOR AUTONOMY More than just temporary help, you will be trained and acquire the necessary skills to take charge of the development of your CV, making my service a real investment in your future. ▪ ADVANCED HR COMPLIANCE Your new optimized CV will be tested using HR research tools, identical to those used by recruiters, thus ensuring its relevance and it will be proofread by a recruitment specialist from my professional network. ▪ A SATISFACTION GUARANTEE 7 days is offered to you upon receipt of your finalized CV. During this period, any modification request may be sent by email or telephone, according to your preferences. One of the strengths of my methodology lies in understanding the often unexpressed subtleties of the world of recruitment, as well as in my ability to formalize these nuances specific to your sector and profession. This expertise will position your application in a way that will capture more of the attention of recruiters and key decision-makers. Thanks to this approach, proven many times, I am confident in the possibility of doubling the number of interviews you will obtain.
