The interaction between which protein and ion initiates muscle coupling?

Biology
1 answer:
labwork [276]3 years ago
3 0

Answer:

Troponin and calcium ions.

Explanation:

Troponin is a component of thin filament along with tropomyosin and actin. It is a protein complex to which calcium binds and start the production of muscular force.

Calcium also playing a very important role in muscle contractions, it binds with troponin and helping to move tropomyosin.

When calcium ion attached to troponin, then conformational changes occurs in troponin shape and moves which allow tropomyosin going away from its inhibitory position from the myosin-binding sites on actin. After this, the energized myosin head starts binding to the actin molecules and starts the cross bridge cycle, which helping in shortening the muscle's fiber.

Based on the results of this study, what questions remain unanswered? How can these questions guide future research?

Answer: One of the biggest questions is, Can we replicate these results in other plants? So, there needs to be more research to determine whether this technique is effective in food crops. It’s not known what the protein PsbS does, even though it seemed to enhance plant growth. There should definitely be more research to find out how this protein is linked to plant growth and whether boosting this protein will affect growth in other types of plants. The researchers also noted that there are numerous other ways to make photosynthesis, and there are more than 100 chemical reactions involved in the process. Investigating other possibilities might be the key to improving crop yield in a wide variety of crops.

Compounds consist of atoms of different elements. In compound the atoms are present in fixed proportion. By changing the proportion compound will changed. For example,

Nitrogen and oxygen reacted to form the compound. By changing the proportion both will form different compound.

NO₂

Nitrogen dioxide consist of one atom of nitrogen and two atoms of oxygen. Their ration is 1 :2

NO

In nitric oxide one atom of oxygen and one atom of nitrogen are present.

Their ratio is 1 : 1.

N₂O

Nitrous oxide consist of two nitrogen atoms and one oxygen. Their ratio is

2 : 1

N₂O₄

Dinitrogen tetroxide consist of two nitrogen atoms and four oxygen atoms. Their ratio will written as 2 : 4

N₂O₅

Dinitrogen pentoxide consist of two nitrogen atoms and five oxygen atoms. Their ratio will written as 2 : 5

Look at the table you filled in above. How does the numbers for how much the snakes are consumed compare to how much these preda
S_A_V [24]

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

<h3>What is a food chain?</h3>

Food chain is the sequence of matter and energy transfers as food from one organism to another.

Food chains interconnect locally into a food web as most organisms consume more than one type of animal or plant.

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

Thus, it can be concluded that this is the main reason behind the number of snakes consumed as compared to other organisms.
