grin007 [14]

Answer: Option B) allosteric activation

Energy required by the cell is generated in the form of ATP. ATP is hydrolyzed to power many of the cellular processes, increasing the pool of ADP. As the relative amount of ADP molecules increases, they can bind to glycolytic enzymes, which will lead to the production of more ATP. The best way to describe this mechanism of regulation is allosteric activation

Explanation:

Some enzymes have more than one active site. The other site(s) is called allosteric site.

In this case, ADP released from the glycolytic reactions binds to the allosteric sites of glycolytic enzymes, activating them and causing further breakdown of glucose, hence ATP continues to be generated.

ATP + H2O ---> ADP + Pi + free energy

Which part of the cell does this illustration represent?
Tju [1.3M]

Answer:

Mitochondria

Explanation:

The mitochondrion is an organelle found in both animal and plants cells. However, it is not found in prokaryotic cells. The mitochondrion is most famously known as the powerhouse of the cell because it produces ATP. The defining visual feature of mitochondria is the wavey-like pattern within the organelle.

In order to understand how the food you eat helps to fuel your body during exercise, you must first be able to use the vocabular
gtnhenbr [62]

Answer:

1. Cardiorespiratory exercise, also known as aerobic

exercise, uses oxygen and typically involves using large muscle groups during continuous activities.

2. Your body produces energy under anaerobic conditions during the first few seconds of intense exercise.

3. When the end phosphate is hydrolyzed from an ATP molecule, ADP is formed, and energy is released.

4.  CP  (Creatine phosphate) is stored in the muscles and is broken down to replenish ATP stores.

5. When participating in low-intensity activities over a long period of time, the body primarily uses fat for energy.

6. A small amount of amino acids

can be utilized for energy production during endurance events, but their primary role is to promote muscle growth and help with repair.

<em>7. Your body burns </em><em><u>carbohydrates</u></em><em>  for energy during every type of exercise that lasts longer than three seconds. Intensity and duration of exercise will affect the percentage of energy that is derived from this source.</em>

8. Endurance athletes may use a training strategy known as carbohydrate loading  to maximize their body's glycogen stores.

9. The body's preferred carbohydrate source for energy during very high intensity exercise is muscle glycogen.

Explanation:

The correct question includes the following incomplete sentences:

1. Cardiorespiratory exercise, also known as ________ exercise, uses oxygen and typically involves using large muscle groups during continuous activities.

2. Your body produces energy under _______ conditions during the first few seconds of intense exercise.

3. When the end phosphate is hydrolyzed from an ____ molecule, ADP is formed, and energy is released.

4.  ____ is stored in the muscles and is broken down to replenish ATP stores.

5. When participating in low-intensity activities over a long period of time, the body primarily uses ____ for energy.

6. A small amount of _______ can be utilized for energy production during endurance events, but their primary role is to promote muscle growth and help with repair.

7. Your body burns _______for energy during every type of exercise that lasts longer than three seconds. Intensity and duration of exercise will affect the percentage of energy that is derived from this source.

8. Endurance athletes may use a training strategy known as _________ to maximize their body's glycogen stores.

9. The body's preferred carbohydrate source for energy during very high intensity exercise is _________.

Words to complete are:

  • <em>anaerobic</em>
  • <em>carbohydrate loading</em>
  • <em>ATP</em>
  • <em>carbohydrates</em>
  • <em>aerobic</em>
  • <em>amino acids</em>
  • <em>fat</em>
  • <em>muscle glycogen</em>
  • <em>CP</em>

Physical exercise involves the additional consumption of oxygen and nutrients to compensate for the increased energy demand that such activity entails.

In general, the body uses the energy metabolism to obtain the energy necessary to carry out its functions.Under normal conditions, energy in the form of ATP is obtained from glucose, a carbohydrate, which requires oxygen, to perform aerobic metabolism.

The different types of physical exercise will require, according to their intensity and duration, alternative metabolic pathways, which include the use of lipids and proteins as an energy substrate, as well as anaerobic metabolism, which does not require oxygen, but whose energy output is lower.

The body's carbohydrate reserves are found in the liver and muscle tissue in the form of a glucose polymer called glycogen. Carbohydrate loading is a technique used by high-performance athletes to store as much glucose as possible, with a special and appropriate diet of low-calorie carbohydrates.

Creatine phosphate (CP) -found in muscle- is a donor molecule of phosphate groups, necessary for the production of ATP, through the action of the enzyme creatine phosphate kinase (CPK).
