In the Z-scheme is the initial electron donor and is the final electron acceptor. A. Water; NADP B. NADPH; oxygen C. Water; oxygen D. ATP; carbon dioxide

Explanation:

Z scheme also known as non cyclic electron flow which starts with the absorption of light by photosystem II

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.
