Yes. So long as the function has a value at the points in question, the function is considered defined.
The protein pump is active in its function.
Yes, exocytosis requires energy to function.
It depends on the organism and cell type. I will assume you mean the human and all cells in general. In this case generally, it is the production of ATP for use. Yes, creating ATP takes energy, and copious amount of it. The biggest problem is the leakage of H+ ion from the intermembrane space into the matrix, which the H+ pumps must constantly work against. This process creates heat, which is inefficient and also one reason why humans are warm-blooded.
principle of complementarity of structure and function
mitrochondria
In the mitrochondria!
kidney
yes
Out, because it "makes" water (by burning hydrogen).
mitrochondria is responsible for protein synthesis in cell
Yes it does. A heterotroph has a mitrochondria because it is needed to break down glucose to get ATP
Cells that require a lot of energy for daily activities, such as muscle cells.
Mitochondria produces energy by breaking down ATP into ADP.
ATP (converted to ADP). Aerobically it is converted back by mitrochondria by oxidizing hydrogen.
The mitochondria looks like the size of a Lima bean inside its cell. So imagine the cell as the size of your hand, then picture a Lima bean in your hand. That is approximately the size of the mitochondria inside the cell (your hand).
Yes, in fact only a very small minority of cells lack these organelles. Mitochondria are vital in respiration, to release energy. Nerve cells require energy to send impulses throughout the body.
