Identfy the incorrect statement about active transport. a)It doesn't require the use of a cell's energy b)None of the choices. c)It moves substances across the cell membrane against their concentration gradients d)Sometimes active transport involves the use of carrier proteins to transport substances in much the same way as passive transport.

None of the choices

Explanation:

Active transport is a process by which substances move through the cell membrane using energy against the concentration gradient. Sometimes there is involvement of carrier proteins.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
