Document Summary

Metabolism: is the buildup and breakdown of nutrients within a cell. Catabolism: the process by which a living organism obtains its energy and raw material from nutrients (energy releasing process) Anabolism: the process by which energy and raw material are used to build cellular structures (energy using process) Catalysts speed up chemical reactions without being altered. Competitive inhibitors fill the active site of an enzyme and compete with the substrate. Non-competitive inhibitor interacts with another part of the enzyme (allosteric site) rather than the active site in a process called allosteric inhibition. Feedback inhibition: end product of a reaction allosterically inhibits enzymes from earlier in the pathway. Redox reaction: an oxidation reaction paired with a reduction reaction. Atp is generated by the phosphorylation of adp with the input of energy. Atp is a nucleotide with three phosphate groups linked in a small chain. The oxidation of glucose to pyruvic acid produces 4 atp and 2 nadh.
