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.

The evidence in the myths "The Maori:Genealogies and Origins in New Zealand" and also the "The Raven and the First Men: The beginnings of the Haida" shows about the Maori and Haida cultures are; they are similar than different because they have important values in common. This will make the correct answer A.
When something needs to be transported against its concentration gradient, or a molecule is too big to simply diffuse through a membrane, active transport has to be used. So active transport requires energy (ATP).
Examples:
1. Antiport pumps: transport one substance in one direction while transporting another substance the other way. An example of this is the sodium-potassium pump.
2. Symport pumps - uses a substance that wants to move from an area of high concentration to low concentration and carries another substance against its concentration gradient. An example of this is the sodium-glucose transport protein
3. Endocytosis - large amounts of extra cellular fluid can be taken into a cell - needs ATP to bind proteins in the cell membrane and causes them to change their shape...which eventually causes the surrounding of the fluid to be brought in (a vesicle).
4.exocytosis - opposite of above
Answer:
Complementary deoxyribonucleic acid (DNA) is DNA in which the sequence of the constituent molecules on one strand of the double stranded structure chemically matches the sequence on the other strand. A useful analog is to picture a key and a lock. ... Complementary DNA (cDNA) is a copy of a region of a strand of DNA.

A, because of the harsh weather and extreme heat, the ablility to burrow underground is helpful for the shade and protection from the sun and also other animals. Hope this helps!
