Osmosis describes the movement of water across a biological membrane and down its concentration gradient. In chemiosmosis, useful energy is harnessed by the cell from the movement of across the inner mitochondrial membrane into the matrix a concentration gradient.

A)ATP, against
B)protons, down
C)electrons, down
D)ADP, against

B)protons, down

Explanation:

Chemiosmosis is the diffusion of ions through a selective permeable membrane. It specifically refers to the production of ATP through the movement of hydrogen ions through an inner membrane during cellular respiration. Hydrogen ions diffuse from an area of high proton concentration to one of lower concentration.

answer: c.

explanation:

the cost of mining is extremely low compared to the money earned from mining, creating income to improve the environment.
