When is acetyl coa produced? a. in photosynthesis b. during glycolysis c. during pyruvate processing d. in the electron transport chain

C. During pyruvate processing

Explanation:

Acetyl CoA is the initiator of the citric acid cycle which is formed by the end product of the glycolysis that is pyruvic acid. It is the link between glycolysis and the citric acid cycle.

Each pyruvate is processed in this process to release one molecule of CO₂, and the remaining two carbon molecule is formed Acetyl CoA.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
