Question

from the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis. drag each compound to the appropriate bin. if the compound is not involved in glycolysis, drag it to the
ot input or output\ bin. view available hint(s)

Explanation:

Glycolysis is the metabolic pathway that breaks down glucose.

• Net Inputs: Glucose is the starting molecule. \(NAD^+\) is reduced to \(NADH\) during glycolysis (but \(NAD^+\) is consumed, so it's an input in terms of the reactant that gets converted). \(ADP\) is phosphorylated to \(ATP\), so \(ADP\) is an input (as it's the precursor for the ATP produced).
• Net Outputs: Pyruvate is the end - product of glycolysis. \(ATP\) is generated (net 2 ATP per glucose molecule). \(NADH\) is produced from \(NAD^+\).
• Not Input or Output: Acetyl CoA is involved in the citric acid cycle (after pyruvate is converted to acetyl CoA). \(CO_2\) is produced in the citric acid cycle (not in glycolysis). Coenzyme A is mainly involved in the formation of acetyl CoA (from pyruvate). \(O_2\) is used in oxidative phosphorylation (not in glycolysis).

Answer:

• Net Input: \(NAD^+\), \(ADP\), glucose
• Net Output: pyruvate, \(ATP\), \(NADH\)
• Not Input or Output: acetyl CoA, \(CO_2\), coenzyme A, \(O_2\)
