Under what conditions will the body use significant amounts of protein for energy during exercise?a.Inadequate calorie intakeb.I
irga5000 [103]

Answer:

Hello!

The answer is b. inadequate calorie intake and inadequate carbohydrate storage

Explanation:

Our body requires energy to carry out daily activities and body functions. This energy is available to the body in three forms:

  1. carbohydrates
  2. fats
  3. proteins

Carbohydrates are the first and most readily available source of energy as starch and complex carbohydrates and sugars are immediately broken down into glucose which is available for body cells. Excess glucose is also stored as glycogen in the muscles. During exercise, carbohydrates, particularly, glucose are the first sources of energy for the body.

Fats provide the highest energy of all three (9 kilocalories compared to 4 of protein and carbohydrates). Fats are stored in the body in the form of adipose tissues or body fat. Any excess energy is readily stored by the body in the form of fats.

As proteins are not stored by the body, they are the last to be broken down during strenuous or prolonged exercise. Protein, particularly the skeletal muscle is the last to be used for energy in case of low calorie intake and inadequate carbohydrate stores.

What is the end result of the electron transport chain?
WARRIOR [948]

Answer:

The end result is Water and ATP.

Explanation:

Electron transport chain is the stage of cellular respiration. Four protein complexes in the inner mitochondrial membrane form the electron transport chain. These complexes exist in a descending order of energy. The electron carriers come along to drop off all their electron and proton cargo that they picked up during the glycolysis and citric acid cycle stages.he electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.

Alexxx [7]

Answer:

Leo is suffering from a condition known as <u><em>obsessive-compulsive disorder</em></u>.

Explanation:

The obsessive-compulsive disorder refers to an anxiety problem characterized by intrusive, recurrent and persistent thoughts that might produce worry, concern, and repetitive actions or behavior, known as <u>compulsions</u>. These compulsions are directed to reduce the associated <u>anxiety</u> and to avoid that something bad occurs.

A pattern of thoughts and irrational fears -<u>obsessions</u>- that make the patient behave with repetitive actions -<u>compulsions</u>-, characterize this disorder.

These obsessions and compulsions interfere in daily activities and are the cause of anxiety and distress.

This disorder is expressed by different symptoms,  such as obsessive cleaning, washing, ordering, accumulating, among others. The exposed example is the case of a verifying person who needs to verify everything to avoid a catastrophe. They need to check that doors are closed, or electro domestics are in their off mode.
