Document Summary
Week 1: explain the importance of atp in energy transfer. List two specific enzymes that help to establish the rate of atp demand during exercise and two specific substrates that are catabolized for atp resynthesis. Atp can help convert energy into usable forms for the muscle and non-usable heat energy. Atp demand ca2+, na+/k+ or myosin atpases. Substrates pcr, glycogen (muscle), glucose from liver glycogen, faa from muscle or adipose tg, or the bcaa: explain the role of enzymes in energy transfer. Give two specific examples of exercise situations in which enzyme function is altered (increased or decreased). Increase the rate of the chemical reaction by reducing the activation energy required. Increased with increased body temp if exercising at intensity/duration that increases body temp. Decreased at high intensity when ph is decreasing. Increased in certain rate determining enzymes when adp concentrations increase (stimulator: explain why a 400 m runner might ingest sodium bicarbonate prior to a race.
