Samuel ate some vegetable soup. <u>Digestion</u> process is at work to allow Samuel to break down the soup so that his body will be able to produce energy.
<u>Option: D</u>
<u>Explanation:</u>
There are majorly four steps in food processing in human body, these are ingestion, digestion, absorption and elimination. There are six major phases covered by digestion: ingestion, acceleration, mechanical or physical digestion, chemical digestion, absorption and defecation. The first of these procedures, ingestion, relates to the absorption of food via the mouth into the food canal.
Digestive system allow the transformation of massive insoluble food molecules into small water-soluble food components to dissolve them into the watery plasma of the blood. Many smaller particles are ingested into the bloodstream in certain species through the small intestine.
Answer: B. In hypoxic tissues, in contrast to normoxic tissues, ATP is additionally consumed to transform lactate to pyruvate
Explanation:
In hypoxic tissues such as new cancerous cells, the vascular system is still underdeveloped, thus oxygen supply is reduced. To meet energy need, additional glucose is needed to convert lactate (result of anaerobic glycolysis) to pyruvate which can then go into the TCA cycle to yield energy. This phenomenon is very common in muscle tissues during exercise.
