Which of the following is not a way in which an enzyme can speed up the reaction that it catalyzes? the active site of the enzyme can provide a microenvironment that facilitates the reaction. the enzyme can heat the substrate. the enzyme binds a cofactor that interacts with the substrate to facilitate the reaction. the binding of two substrates in the active site provides the correct orientation for them to react to form a product. binding of the substrate to the active site can stretch bonds in the substrate that need to be broken.

The binding of two substrates in the active site provided the correct orientation for them to react to form a product

hello there the answer is d

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.
