Answer
While NAD+ is converted into NADH during glycolysis, this process occurs in specific reactions and is not the primary function attributed to the structure labelled Y.
Step 3
C. the majority of ATP is produced in the cell.

Answer
This is the correct statement. The structure labelled Y likely refers to mitochondria, where oxidative phosphorylation takes place, generating the majority of ATP in cellular respiration.
Step 4

Answer
This statement pertains to the process of pyruvate decarboxylation which occurs after glycolysis, thus it does not directly apply to the structure labelled Y.
