topjm [15]

Complete Question:

Cortisol is a hormone produced in response to stress, including starvation, in humans. Which of the following is most likely an immediate effect of a starvation-induced increase in cortisol secretion?

(A) Increased activation of the immune system

(B) Increased urine production by the kidneys

(C) Increased bone and collagen formation

(D) Increased mobilization of fatty acids from fat cells

Answer: Increased mobilization of fatty acids from fat cells.

Explanation: Cortisol is a hormone produced in response to stress, including starvation, in humans. Immediate effect of a starvation-induced increase in cortisol secretion is the increased mobilization of fatty acids from fat cells (Adipose tissue).

Starvation occurs when an animal doesn't feed due to unavailability of food. The body system makes use of stored glycogen which is synthesized to glucose by hormonal secretion of glucagon by the pancreas.

However, when the glucose converted is finished. Cortisol is secreted, which then initiate the mobilization of fatty acids as source of energy from the adipose tissues (fat cells) in the body system.

Contact [7]
<h2>Answer </h2>

Lactic acid fermentation ocurrs in muscle cells when oxygen is in low supply

<u>Explanation</u>

The lactic acid fermentation in the muscles cell occurs when muscles work faster and it occurs due to the lack of supply of oxygen in the cell. The lactic acid fermentation is a type of aerobic respiration. The lactic acid formation is due to excessive exercise by individuals and oxygen which is essential for living, is less in the muscle which causes the feeling of burning in the muscles.

Roughly how many more atp’s can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysi
Lubov Fominskaja [6]

Roughly 15 times more ATP can be produced via the complete aerobic oxidation of glucose compared to that produced by glycolysis alone.

<h3>What is Glycolysis?</h3>
  • The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH).
  • A series of ten enzyme-catalyzed processes make up glycolysis. the binding energy of carbs is captured. One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid).
  • Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route.
  • In fact, the events that makeup glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, likewise in the absence of enzymes, and are catalyzed by metal.
