Explanation:

(3) active transport

The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.

While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.

Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

Angiotensin-converting enzyme (ACE) inhibitors and other vasodilators are used in the early treatment of heart failure. They act

Iteru [2.4K]

Answer:

Option c. cause pooling of the blood and decreased venous return to the heart

Explanation:

The ACE inhibitors increases the diameter of the blood vessels (vasodilation) that improves the flow of blood. This reduces the work load on the heart. At the time of heart failure, a substance called angiotensin is released. This angiotensin formation is blocked by the ACE inhibitors. Angiotensin is involved in narrowing the blood vessels.

The ACE cause pooling of the blood and decreased venous return to the heart. The ACE inhibitors causes vasodilation that allows decrease in blood pressure. So, there is no increase in arterial pressure, aldosterone and loss of volume. Thus, option C is correct.
