why do heart cells have a higher percentage of mitochondria than liver and pituitary gland cells?

Answers

Answer:

This is because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

The heart cells have a higher percentage of mitochondria than liver and pituitary gland cells because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

What is the role of mitochondria in producing energy?

The role of Mitochondria in producing energy are in charge of producing energy as ATP. The heart muscle has the highest energetical requirements. Several mitochondria compose these muscle cells because too much energy is needed to pump blood constantly.

Mitochondria are known as the one of the biggest organelles in the cell. They are semi-autonomous organelles surrounded by a double membrane that reproduce by binary fission and contain their own DNA, RNA, and ribosomes. Mitochondria are in charge of aerobic cell respiration, the process by which cells use organic compounds and turn them into energy.

Therefore, The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

the small bones in the middle ear that transmit vibrations to the inner ear

Answers

Answer:

, yes..............

Explanation:

because the vibrations are transmitted to the inner ear after the bones amplify it

Ossicles are the body's tiniest bones. the malleus (hammer), incus (anvil), and stapes (stirrup). Ossicles amplify sound. 

What are ossicles?

Ossicles are very little bones; in fact, they are the tiniest bones in the entire human body. The malleus (hammer), the incus (anvil), and the stapes are the names of the three bones because of the forms they make (stirrup). The sound is amplified even further by the ossicles.

In order to reach the eardrum, sound waves must first enter the outer ear and then proceed via the ear canal, which is a very short conduit. The incoming sound waves cause the eardrum to vibrate, and the eardrum in turn transmits these vibrations to three very small bones located in the middle ear. The malleus, incus, and stapes are the names given to these three bones.

Hearing is dependent on a series of intricate steps that convert sound waves in the air into electrical impulses. These steps are necessary for hearing.
