Which of the following is a difference between primary and secondary active transport?
primary active transport is used to transport sugars and amino acids across the plasma membrane, while secondary active transport includes the sodium-potassium pump.
primary active transport is driven by secondary active transport.
energy is required for primary active transport, but energy is not required for secondary active transport.
in primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated.

In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

i didn't have the answer choices , but i tried my best.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
