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.

Determine if the following statement is true or false. If true, choose TRUE. If false, choose the rewording that is true. Becaus
pickupchik [31]

The given statement is True.

The transport process that does not requires the consumption of ATP molecules is called as passive transport. The movement of solute molecules along the concentration gradient (from higher concentration to lower concentration) is called diffusion. This process does not requires ATP for the movement of molecules from one place to another.
