Answer:

Hydrochloric acid contributes to protein digestion by supplying H+ which activates pepsinogen, the precursor to pepsin. Pepsinogen is secreted by chief cells in the gastric glands of the body and antrum of the stomach.

Answer:

Activates pepsin enzyme

Explanation:

  • Carbohydrates are digested into maltose in the mouth and protein digestion begins in the stomach.  
  • In the stomach, food undergoes chemical as well as physical digestion.
  • Due to the peristaltic action of the muscles the bolus breaks up in the stomach wall and mixes well into a chyme. ( <em>Physical digestion</em> )
  • Several secretions flow into the stomach.
  • It is collectively known as gastric juice.
  • Also the juice contains pepsin and HCL acid.
  • Here, the enzyme pepsin acts on the proteins in the food and forms polypeptides, which are intermediate products of life. ( <em>Chemical digestion</em> )
  • And  the function of the HCL acid  is to stimulate pepsin enzyme and make it active

Which two molecules generated by the Krebs cycle pass their high-energy electrons to the electron transport
Sidana [21]

<u>Answer</u>:

The two molecules generated by the Krebs cycle that pass their high-energy electrons to the electron transport are NADH and  FADH2

<u>Explanation:</u>

The kreb's cycle gives NADH and also the another hydrogen carrier which is termed as FADH2. During the process of the electron transport chain, one NADH gives rise to electrons and also the hydrogen ions, which has enough potential energy that can convert and produce 3 ATP molecules. Again in the electron transport chain the NADH and the FADH2 undergoes oxidation and releases energy in the form of the ATP. The process of generation of the ATP in the electron transport chain(ETC)  is also referred as the chemiosmotic phosphorolation.
