Energy Metabolism Pathways Carbohydrate metabolism is responsible for the formation, breakdown, and interconversion of carbohydr
Ksivusya [100]

Answer:

The glucose conversion to PYRUVATE opens anaerobic and aerobic metabolic pathways. VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. In the Cori cycle, the release of energy from ATP converts lactate to glucose and returns the glucose molecule to the muscles through the process of Anaerobic Glycolysis.

Explanation:

In metabolism, glycolysis is defined as the splitting of the glucose molecule to form two molecules of pyruvic acid. It is the first main metabolic pathway in cellular respiration for the production of energy in form of ATP(Adenosine triphosphate).

In most cells, cellular respiration occurs in the presence of oxygen. This is known as AEROBIC RESPIRATION which produces the largest number of ATP. Energy can also be gotten by breaking down of glucose in the complete absence of oxygen. This is known as ANAEROBIC RESPIRATION.

The next stage in the degradation of glucose is a two step conversion of the two pyruvic acid molecules from glycolysis into two molecules of acetyl coenzyme A( acetyl - CoA). This occurs in the TCA( tricarboxylic acid) or Krebs cycle.

VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. Coenzyme A is a derivative of vitamin B which combines with pyruvic acid to form acetyl CoA , 2 molecules of carbon dioxide and 4 molecules of hydrogen in TCA cycle.

In Cori Cycle, (which is also called Lactic acid cycle), energy released from ATP is used to convert lactate to glucose. This is to prevent increased lactic acid in the blood during anaerobic conditions in the muscles.

Explain the difference between a prokaryotic cell and a eukaryotic cell.​
Oduvanchick [21]

Answer:

Eukaryotic cells have a membrane-bound nucleus.

Prokaryotic cells do not. The nucleus is where Eukaryotic stores their genetic information.

A) Compare and contrast diffusion, passive transport (diffusion &amp; facilitated), primary active transport and secondary activ
zheka24 [161]

Answer:

<u>Passive transport</u>: It does not need any energy to occur. Happens in favor of an electrochemical gradient. Simple diffusion and facilitated diffusion are kinds of passive transport.

<u>Simple diffusion</u>: molecules freely moves through the membrane.

<u>Facilitated diffusion</u>: molecules are carried through the membrane by channel proteins or carrier proteins.

<u>Active transport</u> needs energy, which can be taken from the ATP molecule (<u>Primary active transport</u>) or from a membrane electrical potential (<u>Secondary active transport</u>).

Explanation:

  • <u>Diffusion</u>: This is a pathway for some <em>small polar hydrophilic molecules</em> that can<em> freely move through the membrane</em>. Membrane´s permeability <em>depends</em> on the <em>size of the molecule</em>, the bigger the molecule is, the less capacity to cross the membrane it has. Diffusion is a very slow process and to be efficient requires short distances and <em>pronounced concentration gradients</em>. An example of diffusion is <em>osmosis</em> where water is the transported molecule.
  • <u>Facilitated diffusion</u>: Refers to the transport of <em>hydrophilic molecules</em> that <em>are not able to freely cross the membrane</em>. <em>Channel protein</em> and many <em>carrier proteins</em> are in charge of this <em>passive transport</em>. If uncharged molecules need to be carried this process depends on <em>concentration gradients</em> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an <em>electrochemical gradient</em>. The <em>glucose</em> is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.

<em>Simple diffusion</em> and <em>facilitated diffusion</em> are <u>passive transport</u> processes because the cell <u><em>does not need any energy</em></u> to make it happen.

  • <u>Active transport</u> occurs <em>against the electrochemical gradient</em>, so <u><em>it does need energy to happen</em></u>. Molecules go from a high concentration side to a lower concentration side. This process is always in charge of <em>carrier proteins</em>. In <u>primary active transport</u> the <em>energy</em> needed <em>comes from</em> the <em>ATP</em> molecule. An example of primary active transport is the <em>Na-K bomb</em>. In <u>secondary active transport</u>, the<em> energy comes from</em> the <em>membrane electric potential</em>.  Examples of secondary active transport are the carriage of <em>Na, K, Mg metallic ions</em>.
