Human skeletal muscle Mitochondrial Function?

Question

Can anybody explain the differances between mitochondiral function, metabolic pathways and enzyme activity. A brief description on each as well would be much appreciated.

Answer 1

Mitochondria contain the electron transport chain. This chain converts the energy from the diet into ATP - the form of energy used by the cell.

Metabolic pathways are any/all of the chemical pathways in the body that either build molecules (anabolism) or breakdown molecules (catabolism). These pathways are 'run' by various enzymes.

Enzyme activity is the specific action of any given enzyme. Enzyme activity increases the efficiency of the various chemical reactions involved in anabolism and catabolism.

Hope this is helpful. Best wishes.

Answer 2

All mitochondris are power genertaing house of the cell.It contain NADPH and it oxidize the pyruvate (generated by the glycolysis pathway in the cellular cytoplasm).It has 2 menbranes and on it's inner membrane contain proton pumps which phosphorylate the ADP to ATP which is the energy currency of the all biologic activities.

Answer 3

The only job of a skeletal muscle cell is to contract on our command. When we use our muscles to move, lift things, etc. we are simply contracting groups of muscle cells all at one time. Different muscles in our body run along bones in different ways, causing various movements when they contract (e.g. the opposing motion of biceps and triceps). It all begins with that one little muscle cell.

Answer 4

there's no real BRIEF explanation for any of the three, I'm in medical school and still don't understand all three extremely well.....try www.wikipedia.org and search each one, there's TONS of information on each one there....good luck!!
