What membrane activities requires energy from atp hydrolysis?
NikAS [45]

Answer:

active transport, like Na + ions leaving the cell

Explanation:

The active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, just as the diffusion facilitated the active transport is limited by the number of transport proteins present.

Two major categories of active, primary and secondary transport are of interest. The primary active transport uses energy (generally obtained from ATP hydrolysis), at the level of the same membrane protein producing a conformational change that results in the transport of a molecule through the protein.

The best known example is the Na + / K + pump. The Na + / K + pump performs a countertransport ("antyport") transports K + into the cell and Na + outside it, at the same time, spending on the ATP process.

The secondary active transport uses energy to establish a gradient across the cell membrane, and then uses that gradient to transport a molecule of interest against its concentration gradient.

A gardener is installing several large flower beds. The flower beds will vary in length from 5 to 12 feet. Depending on the type
dezoksy [38]

The gardener should address the measurements he needs to make so that planting information is clear, and that the roots are spaced to grow.

<h3>How to calculate amount of landscaping plants?</h3>

 just divide the area of the bed by the area occupied by the seedling and we will have the total amount of seedlings to be used. In this way, we also understand that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.

<h3>How to calculate the spacing between plants?</h3>

If we plant with a spacing of 0.60 meters, the number of seeds per meter will be calculated as follows: Being 1 hectare = 10,000 square meters and the spacing between rows of 0.60 m, we have the equivalent of a range of 0, 60 meters by 16,667 linear meters (10,000 divided by 0.60).

With this information, we can conclude that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
