No bc Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP<span>). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called </span>aerobic respiration<span> and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.

The nucleus is still there.
Answer:
F
Explanation:
all the chromosomes in the nucleus replicate their DNA to make identical copies
i hope that i got it right
Answer:
Broad substrate specificity of chymotrypsin would be very dangerous for a protease that plays a role and perform its activities outside of the digestive system.
Explanation:
Chymotrypsin is one of the serine base proteases that includes 3 polypeptide chains. Disulfide bonds held all three polypeptide chains together. Chymotrypsin is a digestive enzyme released by the pancreas into the duodenum.
As a digestive enzyme, chymotrypsin's role is to indiscriminately degrade a large range of proteins that are taken in so that their component AAs can be recovered.
Broad substrate specificity of chymotrypsin would be very dangerous for a protease that plays a role and perform its activities outside of the digestive system.
