Question
Chapter 4, Problem 1AC
Summary Introduction
To determine:
The higher density of mitochondria would be found in the leg tissue samples of which individual, a world-class marathon runner or a sedentary individual.
Introduction:
The mitochondrion is an organelle considered as “the powerhouse of the cell”, which synthesizes energy in the form of ATP (adenosine triphosphate). It is the place in the cell where

Reduced formation of water C.) Reduced activity of electron transport chain D.) Increased activity of ATP synthasearrow_forwardImagine that you are given an unknown cell sample. You visualize the sample under the microscope and you notice that it has a large number of mitochondria. Based on this observation, what can you say about the function of this cell?
