Answer:

The correct order is:

Glycolysis
Pyruvic acid oxidation or pyruvate oxidation (produces Acetyl Co-A)
Citric Acid cycle
Electron Transport Chain (ETC)

Explanation:

In the cytoplasm, the process of glycolysis involves the conversion of 6-carbon glucose into two molecules of pyruvate, producing ATP and NADH as well.
The two pyruvate molecules enter the mitochondrial matrix where they are converted to Acetyl Co-A by the enzyme pyruvate dehydrogenase.
Acetyl Co-A enters the Kreb's cycle or citric acid cycle that generates ATP, NADH and FADH2.
The NADH and FADH2 produced are converted into ATP through oxidative phosphorylation in the electron transport chain.

Where does the H+ come from that makes ATP synthase work?

MissTica

Answer:

Chemiosmosis

Explanation:

The electrons from from NADH and FADH2 pass through the electron transport chain in the mitochondria, donating their electrons and generating a H+ buildup. This generates a proton pump to power ATP synthase. This process is called chemiosmosis.

The portion of the circulation governed by the right side of the heart is the ______ circulation.

AlekseyPX

The correct answer is B. Pulmonary. The answers C. Cerebral and D. Extremity, are baseless regarding this question; A. Systemic could be a good alternative, as the blood flows from the systemic to the pulmonary circulation in the right side of the heart; but the systemic circulation is in fact mostly handled in the left side of the heart, while the right side handles the pulmonary one.
