From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis.

If the compound is not involved in glycolysis, match it to the "not input or output" category.

a) net input

b) net output

c) not input or output

ADP, glucose, ATP, O2, CO2, NAD, NADH, Coenzyme A, Pyruvate, acetyl CoA

ADP - net input

glucose - net input

ATP - net output

O2 - not input or output

CO2 - not input or output

NAD - net input

NADH - net output

Coenzyme A - not input or output

Pyruvate - net output

acetyl CoA - not input or output

Explanation:

Glycolysis is the breaking down of glucose. Glycolysis produces pyruvate, ATP, NADH and water.

The net reaction can be written as:

Glucose+2NAD + 2ADP + 2Pi - -> 2 Pyruvate + 2 ATP + 2NADH + 2H

NAD is reduced to NADH

ATP is produced by addition of Pi to ADP (this is known as phosphorylation). Pi is inorganic phosphorous.
