BIO 353 cell bio exam Practice Questions and Answers The break down of glucose into pyruvate releases less than 25% of the total energy present in glucose. The remaining energy is stored in the resulting (2) pyruvate molecules. In the presence of oxygen, acting as an electron acceptor, complete substrate oxidation is possible. ______ is defined as "the oxidation driven flow of electrons, through or within a membrane, from reduced coenzymes to an electron acceptor, usually accompanied by...

Identify the choice that best completes the statement or answers the question. ____ 1. Which statement regarding the sodium–potassium pump is correct? The cell’s plasma membrane is more soluble to sodium ions than potassium ions. The concentration of sodium ions should be higher inside the cell compartment. The concentration of potassium ions should be higher outside the cell compartment. The active transport involves pumping out three sodium ions and pumping in two potassium ions. ...
