The production of new molecules and the breakdown of old molecules in the cell is calledMultiple choice question.entropy.metabolism.chemical equilibrium.diffusion.

Which process involves the movement of small molecules against their concentration gradient and requires an expenditure of cellular energy?

What substance moves into the cell by diffusion?

Question textTransport of a substance through a cell membrane that DIRECTLY requires the energy supplied by the breakdown of ATP is called: Question 2Select one:a.secondary active transportb.facilitated diffusionc.translationd.diffusione.primary active transport

The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane-bound carrier proteins is called:Question 17Select one:a.osmosis.b.facilitated diffusion.c.active transport.d.endocytosis.e.exocytosis.

An example  of a molecule that uses facilitated diffusion to enter the cell is oxygen starch glucose carbon dioxide
