Cells are limited in size by their suface areas and..?

Biology
1 answer:
weeeeeb [17]3 years ago
7 0
Cells are limited in size by their surface area and volume. A cell does not possess a mouth, lungs and digestive system. Every process has to happen directly or indirectly through the cell membrane. The relationship between the volume of cell contents and the surface area of the cell membrane becomes the limiting factor in how big a cell gets to be. If it gets too big it may starve due to lack of incoming nutrients, or poison itself because it can not get rid of waste rapidly enough.

How do protons contribute towards making ATP?...
ivanzaharov [21]

Answer: Protons contribute towards making ATP by producing proton-motive force that provides energy for ATP synthesis.

Explanation: In the respiratory chain, the transfer of electrons from one complex to another is accompanied by pumping of protons out of the matrix. This creates a difference in proton concentration and separation of charge across the mitochondrial inner membrane. The electrochemical energy inherent in this difference in proton concentration called proton-motive force is used to drive ATP synthesis as protons flow back passively into the matrix through a proton pore.
