Question

Ions are transported across membranes using __________, which requires __________. ions are transported across membranes using __________, which requires __________. simple diffusion; kinetic energy channel-mediated facilitated diffusion; atp energy channel-mediated facilitated diffusion; kinetic energy carrier-mediated facilitated diffusion; atp energy

Answer 1

The correct answer will be options

1. ATP energy channel-mediated facilitated diffusion

2. ATP energy

Step-by-step explanation:

The ions are transported across a biological membrane using ion transporters. These ion transporters are the transmembrane enzymes which use energy from ATP molecules to transport ions against a concentration gradient.

The ATP using channels converts the ATP energy to potential energy stored in the form of electrochemical gradient which is used to drive the process of formation of the ATP using ATP synthase.

Thus, the selected option is the correct answer.

Answer 2

the correct answer is channel mediated facilitated diffusing using kinetic energy. facilitated diffusion is also referred to as facilitated transport or passive mediated transport. in this type of transport, molecules move spontaneously across the plasma membrane through the integral proteins referred to as channels. in facilitated diffusion, molecules convert potential energy to kinetic energy and move from the region of high concentration to the region of low concentration across semipermeable membrane.
