Answer:
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small.
explicación:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
That would be the R-value
Answer;
ATP.
The generation of ATP occurs by Chemiosmosis.
Explanation;
In the electron transport chain, hydrogen ions in the matrix space can only pass through the inner mitochondrial membrane through a membrane protein called ATP synthase.
As these protons move through ATP synthase, ADP is turned into ATP.
The production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosphorylation.
C. transporting nutrients to cells
