AfilCa [17]3 years ago
7 0

Answer:

The nucleus regulates the synthesis of proteins in the cytoplasm through the use of messenger RNA (mRNA). Messenger RNA is a transcribed DNA segment that serves as a template for protein production. It is produced in the nucleus and travels to the cytoplasm through the nuclear pores of the nuclear envelope, which you'll read about below. Once in the cytoplasm, ribosomes and another RNA molecule called transfer RNA work together to translate mRNA in order to produce proteins.

She notices that the muscle cells are loaded with mitochondria while the macrophages have abundant lysosomes. why is this so?
Kaylis [27]

The muscle cells are loaded with mitochondria to allow large amounts of ATP production while the macrophages have abundant lysosomes to digest the debris and dead organisms like bacteria.

Mitochondria are known as the powerhouse of a cell. This is because most of the ATP production used by various systems in their operation is produced by mitochondria. A chemical called NADH is produced in the mitochondrial matrix through the Krebs cycle. The enzymes embedded in the mitochondrial membrane use this chemical to produce Adenosine Triphosphate, generally known as ATP.

Macrophages are phagocytic white blood cells involved in engulfing and killing pathogens. They are involved in the innate immune response of the body. Lysosomes have specialized enzymes that can kill these pathogens.

Muscle cells need to contract or expand for which they require energy. Thus, they have abundant mitochondria. Whereas, the macrophages have abundant lysosomes to help them kill disease-causing pathogens like a virus or bacteria.

To know more about ATP production in mitochondria, refer to the following link:

How do intrusive rocks form?
IgorLugansk [536]

!!•••••••☆☆ Hey mate ☆☆•••••••!!

Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals.

Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals.
