Santiago Neville Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule
