What structure of the sarcomere shortens during muscle contraction?
LiRa [457]

Answer:

The Z lines and H- zone shortens during the muscle contraction.

Explanation:

Sarcomere is the area between the two Z lines. The Z- lines are present in the centre of I - band and H - zone is present in the A - band. The actin filaments which are thin filaments present in I- band and contracts, slide over the myosin filament during contraction.

The I - band, H- zones are became shortens as they are thin than the A- band. It is anisotropic band having thick myosin filaments. They are not flexible and remain in its constant shape during the muscle contraction.

After the muscle contraction, the A- band and the H- zone comes to their original shape. In other words, the sarcomere shortens and comes back during muscle contraction, and relaxation.

jeyben [28]

Due to increase or decrease in the concentration of carbohydrates have no effect on protein concentration.

A diet having 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates because with the increase or decrease of carbohydrates in the diet does not increase the amount of protein.

Compare and contrast transcription and translation
tangare [24]
So first transcription takes place which is a RNA that translates DNA Template. So an example would be DNA has AGCGTCAATCTA this will be translated into UCGCAGUUAGAU

Then this message is send off to become a protein with the MRNA which then comes Translation which is the process of converting UCGCAGUUAGAU into a protein and the way it’s done is by this message going through a ribosome and gets translated by TRNA that brings amino acids together to form codons and create your protein.

What is an essential role played by large intestine bacteria?
Likurg_2 [28]

Answer:

The correct answer is: synthesize vitamin K and B-complex vitamins.

Explanation:

The large intestine, an important region of the gastrointestinal tract, is populated with bacteria that maintain our bodies healthy. The term used to describe these organisms that live in the digestive tract is gut microbiota.

The relationship between humans and the gut microbiota is not only non-harmful but also beneficial to humans. <u>Bacteria ferment dietary fibers into </u><u>short-chain fatty acids</u><u> for us to absorb it</u>. Gut microbiota also plays a crucial role in synthesizing vitamin B and vitamin K, as well as metabolizing <u>sterols and bile acids</u>. These bacteria act much like an endocrine system that regulates intestinal function with the use of short-chain fatty acids, as if they were hormones.

<u>Vitamin K</u><u> is important for</u><u> blood clotting</u><u>, while </u><u>vitamin B</u><u> intervenes in </u><u>cellular metabolism</u>.
