What is ATP? List the three components of an ATP molecule. What is ATP used for?

1 answer:

5 0

ATP(Adenosine Triphosphate) is a small molecule used in cells as a coenzyme. It is often referred to as the "molecular unit of currency" of intracellular energy transfer.

Three components of an ATP molecule:
-At the centre is a sugar molecule,ribose( the same sugar that forms the basis of RNA). Attached to one side of this base(a group consisting of linked rings of carbon and nitrogen atoms) in this case the base is adenine. The other side of the sugar is attached to a string of three phosphate groups.

ATP is used to transport chemical energy within cells for metabolism.

The gradual process during which glucose is broken down to release energy

8_murik_8 [283]

Answer:

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose.

Chemical energy is a form of _____ energy. chemical energy is a form of _____ energy. entropic potential heat motion kinetic

pav-90 [236]

The answer is potential. It is because chemical energy is a storage of energy that are formed in which making it or why it is considered to be potential rather than those given choices above in which doesn’t describe chemical energy.

Describe the stages of each type of cell reproduction process from a normal patient whose body cells can repair themselves and n

Citrus2011 [14]

The types in which cell divides are:

I. Mitosis: Mitosis is the type of cell division in which the DNA and chromosome number of the daughter cell remains the same as parent cell (2n).

Different stages of mitosis are:

a. Prophase - disappearance of nuclear membrane takes place and chromosome starts to condense.

b. Metaphase - The Chromosome aligns to the equatorial plane and gets attached to the spindle fibre arising from the centrioles through its centromere.

c. Anaphase - The sister chromatids of a chromosome gets separated and starts moving to opposite poles.

d. Telophase - Nuclear membrane reappears and the cells divide.

One example where mitosis takes place is to repair the part of the body where it has got injured.

II. Meiosis: Meiosis is the type of cell reproduction where the daughter cell have half the number of chromosome and DNA content than mother cell. Meiosis takes place in two stages and they are:

i. Meiosis I - It includes following stages:

a. Prophase I - Nuclear membrane disappears and chromosome starts to condense.

b. Metaphase I - The homologous chromosome aligns to the equatorial plane and gets attached to the spindle fibre arising from the centrioles through its centromere.

c. Anaphase I - The homologous chromosome gets separated and starts moving to opposite poles.

d. Telophase I - Nuclear membrane reappears and the cells divide.

Meiosis I leads to the formation of two daughter cells.

ii. Meiosis II - It includes following stages:

a. Prophase II - disappearance of nuclear membrane takes place and chromosome starts to condense

b. Metaphase II - The Chromosome aligns to the equatorial plane and gets attached to the spindle fibre arising from the centrioles through its centromere.

c. Anaphase II - The sister chromatids of a chromosome gets separated and starts moving to opposite poles.

d. Telophase II - Nuclear membrane reappears and the cells divide.

Meiosis II leads to the formation of four daughter cells having haploid number of chromosome.
