This should have been more points but I’m not really good with bones
I would say energy myself, and this is because energy plays a key role in all of these. With trophic levels energy is being transferred amongst the levels. Food chain's is a map of how the energy is passed along the chain. Food web is a web of how energy is transferred, and this is why I would say energy is a keyword.
This family of ATPases is structurally related to the pumps that acidify lysosomes and vesicles; however, they usually function in reverse, generating ATP from ADP and Pi using proton gradients across membranes is called F-type pumps.
- The inner membrane of mitochondria and bacterial plasma membranes both contain F type pumps, which are necessary for the generation of ATP.
- It is also known as the ATP synthase complex or Complex V. By letting these protons passively return to the matrix, they use the proton gradient created by the flow of electrons to produce ATP.
- The F1 motor is the ATP turnover motor and,
- In mammals, the F0 motor, which is in charge of ion translocation, has nine subunits, nine of which are likely centered on the membrane's A, B, and C subunits, along with D, E, F2, F6, G2, and 8 subunits.
