physical fitness - ANSWER the ability to perform moderate to vigorous activity without undue fatigue ATP (adenosine triphosphate) - ANSWER the main energy currency for cells. Used to promote ion pumping, enzyme activity, and muscular contraction. The immediate source of energy for body functions. ADP (adenosine diphosphate) - ANSWER A breakdown product of ATP. Synthesized into ATP using energy from foodstuffs and a phosphate group.

adenosine triphosphate (ATP) - energy currency of life, high energy molecule that stores energy we need to do anything. Universal unit of energy exhange NAD+, nicotinamide adenine dinucleotide - coenzyme in all living cells. Required for fundamental biological processes. Oxidized form active transport - requres energy. molecules move against concentration gradient. Ex. protein channels, endocytosis, exocytosis. Can be coupled to exergonic chemical reactions or exergonic movement of molecul...

Biochem Exam 1 Questions and Answers Graded A+ What happens to enzymes when the temperature slightly increases within an optimal range? The enzyme activity increases as the kinetic energy of molecules rises, allowing more frequent collisions between enzyme and substrate. Why do hydrophobic amino acids tend to cluster together in the center of a protein? To avoid contact with water, stabilizing the protein's structure. What is the significance of the "lock and key" model...
