The energy for muscle contraction is most directly obtained from

Biology

Answer: the energy for muscle contraction is directly obtained from ATP ( Adenosine Triphosphate)

Explanation:

ATP is the body's biochemical way to store and transport energy. ATP is not stored in large quantities in the cells, hence the need for a quick production once muscle contraction starts. ATP could be produced from these three biochemical systems by the body. They include:

1.) Through the use of creatine phosphate

2.) Glycogen.

3.) Aerobic respiration.

Answer: it is obtained from Adenosine triphosphate(ATP).

Explanation:

In muscle metabolism, muscle need energy for contraction. This energy is obtained from the Adenosine triphosphate (ATP) present in the muscle. The muscle contain limited quantities of ATP. When it is depleted, ATP need to be resynthesize from other available sources like creation phosphate and muscle glycogen.

Metabolism is the total activities which take place in the body to create energy and other substances for its activities.

Vsevolod [243]

This family of ATPases is structurally related to the pumps that acidify lysosomes and vesicles; however, they usually function in reverse, generating ATP from ADP and Pi using proton gradients across membranes is called F-type pumps.

  • The inner membrane of mitochondria and bacterial plasma membranes both contain F type pumps, which are necessary for the generation of ATP.
  • It is also known as the ATP synthase complex or Complex V. By letting these protons passively return to the matrix, they use the proton gradient created by the flow of electrons to produce ATP.
  • The F1 motor is the ATP turnover motor and,
  • In mammals, the F0 motor, which is in charge of ion translocation, has nine subunits, nine of which are likely centered on the membrane's A, B, and C subunits, along with D, E, F2, F6, G2, and 8 subunits.

What are two main types of posttranscriptional modifications that take place in the mrna of eukaryotes?
erastovalidia [21]

Answer:

Addition of poly A tail and and addition of 5' cap

Explanation:

In eukaryotes, many post-transcriptional modification takes place like 5' capping, polyadenylation, and splicing. In 5' capping 7-methyl guanosine is added toward the 5' end of mRNA by the action of a enzyme called guanyl transferase. This cap protects mRNA from degradation.

In polyadenylation up to 250 adenosine nucleotides are added at the 3' end of the mRNA and it is called poly-A tail. Poly A polymerase is the enzyme that is responsible for polyadenylation.  

Therefore two main post transcription modifications are 5' capping and polyadenylation.

Greenhouse effect is caused by:
kow [346]

Answer:

The answer is C. trapped greenhouse gasses

Explanation:

The greenhouse effect is the warming of the Earth's surface and troposphere (the lowest layer of the atmosphere) produced by the presence of water vapour, carbon dioxide, methane, and other gases in the atmosphere. Water vapour has the greatest impact of the gases classified as greenhouse gases.
