Explanation:

An endergonic reaction is a chemical reaction that is unspontaneous in whiich the standard free energy is positive and energy is absorbed. It requires more energy to start the reaction than to give out. Energy is absorbed from the environment. Enzymes is required to convert endergonic reaction to exergonic hydrolysis of ATP.

Examples of endergonic reaction is endothermic reactions e.g photosynthesis and melting of ice to liquid.

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.

the correct answer is b
