Check Only the Steps That Contribute to the Energy System

Check only the steps that contribute to the energy system of anaerobic metabolism.

A) The body turns to stored glycogen as an energy source.
B) A by-product, glucose, seeps out of the muscle cells into the blood to be used elsewhere.
C) ATP is rapidly metabolized to meet energy needs.
D) Lactate is broken down to supply glucose, which is then metabolized within the muscle cells to generate ATP for muscle contractions without the need for oxygen.
E) During sudden outbursts of activity in intensive, short-time exercise, ATP is stored to meet energy needs.
