Biochemistry and metabolism problems

Prompt

Biochemistry and Metabolism Problems involving biomolecules, enzymes, metabolic pathways, bioenergetics, and chemical processes in living systems. Avoiding and excluding purely chemical thermodynamics or organic synthesis unless the primary task is biological function, pathway logic, or biochemical calculation. • Biomolecules - Identifying structures and properties of carbohydrates, lipids, proteins, nucleic acids, cofactors, and metabolites. • Protein structure and function - Working with amino acid properties, peptide bonds, primary through quaternary structure, folding, binding, and denaturation. • Enzyme kinetics - Computing Michaelis-Menten quantities, Km, Vmax, kcat, catalytic efficiency, inhibition type, and reaction rates. • Cellular respiration - Working with glycolysis, pyruvate oxidation, citric acid cycle, electron transport, oxidative phosphorylation, and ATP yields. • Fermentation and anaerobic metabolism - Identifying fermentation products, NAD+ regeneration, oxygen-independent pathways, and energy yields. • Photosynthetic metabolism - Working with carbon fixation, RuBisCO, C3, C4, CAM pathways, and photorespiration. • Metabolic regulation - Interpreting feedback inhibition, allosteric regulation, covalent modification, pathway control, and energy-state effects. • Bioenergetics - Computing or comparing ATP coupling, redox carriers, free energy changes, proton gradients, and thermodynamic favorability. In this field of biology I want the most difficult and lengthy 5 questions and their step by step answers, and solutions should be like up to step 9-10
