Glycolysis is the first stage of cellular respiration and is an anaerobic process. During glycolysis, glucose is converted to tw
o molecules of pyruvic acid. How is glycolysis kept functioning during cellular respiration?
A Two high-energy electrons are passed to the carrier NADH, which transports electrons back to glycolysis.
O
B. Two molecules of ATP from the cell are invested at the beginning of the process of glycolysis.
C. Pyruvic acid from glycolysis reacts to form acetyl-CoA, which then combines with a four-carbon compound in the Krebs cycle and re-enters
glycolysis.
D. Hydrogen ions pass back across the mitochondrial membrane through chemiosmosis and re-enter glycolysis.
Here's a graph showing the stages. Look closely at the second stage-- the death rate is low but the birth rate is high. It's <span>D. The death rate begins to fall, but birth rates remain high for a time.</span>
