Question

Whereas animal cells drive indirect transport with a Na+ gradient, most other organisms use

Answer 1

Animal cells use primary active transport with a sodium-potassium pump, while most other organisms use secondary active transport or co-transport to transport substances into the cell.

Step-by-step explanation:

Animal cells use primary active transport driven by a sodium-potassium pump to create an electrochemical gradient. This pump moves Na+ out of the cell while moving K+ into the cell. On the other hand, most other organisms use secondary active transport, also known as co-transport, to transport substances into the cell. Co-transport takes advantage of the Na+ gradient created by primary active transport to move other substances, such as amino acids and glucose, into the cell.
