What type of transport was shown in the second animation? A. active transport with the help of transport proteins

B. passive transport by simple diffusion across the membrane

C. passive transport by facilitated diffusion with the help of transport proteins

C. passive transport by facilitated diffusion with the help of transport proteins

Explanation:

The electron transport chain (shown in the second animation) establishes a proton gradient across the inner mitochondrial membrane. ATP synthase uses the energy stored in the proton gradient to catalyze the synthesis of ATP. The molecular machinery involved in this process converts chemical energy to mechanical energy and provides a great example of the relationship between the structure and function of macromolecules.

C. passive by facilitated diffusion with the help of transport proteins

Explanation:

Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes.

option number one would be youre best option

answer; i believe that the correct answer is (light);
