Which of the following is not a component of the hepatic triad found at the edges of a liver lobule?
goldenfox [79]

Answer: c) central vein.

Explanation:

The liver is an organ that is present both in humans and in vertebrate animals. It secretes the bile, essential for the digestion of fats, and it also has many other functions, including the synthesis of plasma proteins, storage of vitamins and glycogen and detoxifying function. It is responsible for removing various substances from the blood that may be harmful to the body, including alcohol, making them harmless.

The liver is divided by the sickle cell ligament into two main lobes, right and left. <u>There are two other smaller lobes, the square lobe and the caudate lobe</u>.

The hepatic triads are triangular areas located at the angles of the hepatic lobules, made up of a lax conjunctive stroma. <u>They contain a branch of the hepatic artery</u> (that irrigates the liver<u>),</u> <u>a hepatic portail vein</u> (a thick blood vessel that carries blood from the gastrointestinal tract and spleen to the liver so that nutrients are metabolized<u>)</u> and <u>a bile duct</u> (transports bile into the small intestine). Therefore, it does not contain a central vein.

arlik [135]

Answer: 2; 3

For each FADH2 that supplies electrons to the electron transport system, 2ATPs are synthesized. For each NADH that supplies electrons to the electron transport system, 3 ATPs are synthesized.

Explanation:

Both FADH2 and NADH are you reducing equivalents in that they give off electron in terms of hydrogen atom or a hydride ion.

Thus, in the inner membrane of the mitochondria where electron transport occurs, FADH2 gives off its hydride ion yielding 2 ATP molecules; while NADH gives off its hydride ions to yield 3 ATP molecules
