Question 1

Why do muscle cells contain significantly more mitochondria than skin cells?

Muscle cells have larger nuclei that require less energy.

Skin cells do not use cellular respiration to produce energy.

Muscle cells require more ATP to support continuous contraction.

Mitochondria store calcium, which muscles need to contract.

Required

Question 2

Waste materials and damaged organelles would accumulate in the cell.

The cells would not be able to replicate DNA.

Protein synthesis would increase rapidly.

The plasma membrane would break down.

Required

Question 3

It will be used to form new genetic material .  

It will be broken down so its components can be reused. 

It will be stored for the cell's future energy needs

It will be modified before it is packaged for transport.

Required

Question 4
