Which statement below correctly summarizes cellular respiration? A Using oxygen, cells absorb sunlight and produce glucose.
B ATP is produced in the mitochondria in the absence of oxygen.
C Water is absorbed by the mitochondria, the water is split up into hydrogen and oxygen atoms, and ATP is made.
D Cellular respiration begins with glucose. With the addition of oxygen, energy is made in the form of ATP.

D

Explanation:

It all begins with glucose.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
