Question

When a mitochondrial chaperone helps a mitochondrial matrix protein into the matrix by biased diffusion, the chaperone is said to be acting as ______.

a. Brownian motion
b. biased diffuser
c. Brownian ratchet
d. misratchet
e. unbiased diffuser

Answer 1

c. Brownian ratchet

Step-by-step explanation:

Mitochondria are cell organelles. They are known as the power house of the cells. The energy needed to power the cell is generated by the mitochondria. They functions like a digestive system.

The mitochondria chaperone are proteins that helps the proteins along pathways for their folding. They shield the proteins from other proteins and protect them from binding the folding process. The chaperone are mainly concern with the folding of protein.

The chaperone acts as a Brownian ratchet as the mitochondrial chaperone guides the matrix protein into matrix by the biased diffusion process.
