Enzymatic reactions - Study guides, Class notes & Summaries

Enzymes – Biochemistry Questions and Answers with Verified Solutions What is the primary function of enzymes in biological systems? Enzymes act as catalysts, speeding up chemical reactions without being consumed in the process. How do temperature and pH affect enzyme activity? Enzymes have optimal temperature and pH ranges where they function best; deviations can lead to reduced activity or denaturation. What is the active site of an enzyme? The active site is the specific re...

processing of peptide hormones - ️️1. preprohormones are synthesized from rER and migrate to Golgi in membrane bound vesicles 2. while in ER and golgi, preprohormones are processed into prohormones followed by active hormones 3. golgi packages and labels hormones into secretory vesicles that are stored in cytoplasm until appropriate signal 4. upon signal, vesicle membrane fuses with plasma membrane and peptide hormone is exocytosed major processes the endocrine system can regulate in...

Nutrition definition - correct answer the process of providing or obtaining the food necessary for health and growth. Digestion definition - correct answer It is the catabolic process that breaks down large food molecules to monomers (chemical building blocks) -carbohydrates—> monosaccharide -proteins—> amino acids -lipids—> fatty acid, Glycerol -nucleic acids—> nucleotide *the enzymatic breakdown of any food molecule is HYDROLYSIS bc it involves adding a wate...

How does substrate/enzyme concentration affect enzymatic activity? - ️️If there is too much substrate compared to the enzyme, enzymatic activity will plateau Increasing the amount of enzymes will increase the rate of enzymatic activity How do enzymes catalyze reactions? - ️️By forming a substrate-enzyme complex. The enzyme brings the substrates together and put stress to break the bonds. Enzymes create a micro-environment or break bonds What is a catalyst? - ️️A substance that ...

Properties of all cells - growth, metabolism, and evolution. growth - multiply within hours metabolism - capture light energy by doing enzymatic reactions evolution - changes in their DNA that encodes differences that change over time.
