Question

We would expect cells found in the active muscles of animals to contain relatively large amounts of which cellular organelle?

A) centrioles
B) mitochondria
C) lysosome
D) nuclei

Answer 1

Answer: B) mitochondria

Step-by-step explanation:

In animals the functioning of the muscles requires a lot of energy. This energy is generated by the mitochondria which is called as power house of the cell. Numerous mitochondrial cells are present in the muscles which are responsible for cellular respiration. In this process the energy reservoir glucose is used to produce energy currency molecules called as ATP. The mitochondria produce instant energy by pumping numerous ATP molecules.

Answer 2

B) mitochondria

Step-by-step explanation:

Muscle cells require energy in very high amount because most of the time they are involved in mechanical work i.e. movement and for movement we require large amount of energy. Also, we know that mitochondria are the 'powerhouse of the cell' because they are involved in ATP production which serves as energy source in our body. They are able to produce ATPs with the help of ATPase pump which are located in inner mitochondrial membrane. So, cells found in the active muscles of animals must have large amount of mitochondria so as to perform their function efficiently.
