During exercise, what do muscle cells immediately use as the energy source for contractions?.

Biology
1 answer:
blagie [28]1 year ago
6 0

During exercise, muscle cells immediately use ATP as the energy source for contractions.

The only immediate source of energy for muscular contraction is ATP. Within muscle fibers, ATP is replenished by creatine phosphate (anaerobic respiration), glycolysis (anaerobic respiration), and cellular respiration (aerobic respiration). As the duration and intensity increase, carbohydrates (glucose/glycogen) become the primary source of fuel. If exercise is sustained for an extended period of time, fatty acids will be used as a fuel source when glycogen stores are nearly depleted.

ATP is a form of instant energy. The body cannot obtain energy directly from glucose. Glucose is not a direct source of energy. Instead, the body uses the energy released from the breakdown of glucose to drive ADP phosphorylation.

Choose all the pieces of individual evidence.
faust18 [17]
Criminal evidence is any physical or verbal evidence presented in court to prove a specific crime. Evidence can take different forms and can be used by the accused to prove innocence. Admissible evidence, moreover, is the use of testimony (oral or written such as affidavit), exhibits (physical objects), documentary material or demonstrative evidence ( in the form of representation of an object including photos, x-rays, videotapes, movies, sound recordings, diagrams, forensic animation, maps, drawings, graphs, animation, simulations or models). All are presented before a judge or jury to prove a point or element in a case. In the choices above, six of them can qualify as individual evidence except numbers 3. Number 8, however, is questionable since it has incomplete description as to where and how is the paint was chipped.

What would happen to a deep sea fish brought rapidly to the surface? Explain your answer in light of the fact that gas pressure
Ann [662]

Answer:

Its gas-filled swim bladder explode.

Explanation:

The gas-filled swim bladder of deep sea fish is explodes when brought to the surface too rapidly because in the deep sea there is high pressure on the gases that is present in its tissue so when the fish is brought to the surface too rapidly, the high pressure is removed and the gases that were compressed in the tissue of the fish in deep sea are releases to expand that causes explode of gas-filled swim bladder. There is very high pressure in the atmosphere when we go deep into the sea which put pressure on the lungs of humans and gas-filled swim bladder of fishes which decrease its volume.

Which qualities describe the entire open-ocean zone? Check all that apply. few nutrients
uysha [10]

<u>Answer:</u>

- few nutrients

- high pressure

- low temperatures

<u>Explanation:</u>

1. Few nutrients:  open-ocean zone is located way far from the land, which is the main source of the essential nutrients.

2. High pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.

3. Ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface.

4. Varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.

5. Low temperatures:  the temperature of open-ocean zone ranges from a low of -2°C to an average of 17°C.

Ipatiy [6.2K]

When pieces of the granite get broken off and carried to a new place by weathering and erosion, the pieces can get deposited in the bottom of a lake or sea. Over time the sediments get compacted and cemented together to become sedimentary rock. Sandstone, limestone, and conglomerate can form this way.
