c) glucose
d) a and b.
e) a, b, and c

A. ATP

Explanation:

The Cyclic electron flow in the chloroplast includes only PSI and does not produce NADPH and oxygen gas. The process produces the only ATP.

During cyclic electron flow, electrons are transferred from the P700 reaction center to the ferredoxin and back to the PSI via cytochrome b6f and plastocyanin.

Since the electrons are not passed to the NADP+, NADPH is not produced. The proton gradient generated during this electron transfer drives ATP synthesis.

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.
