Where are lysosomes most abundant?

Lysosomes are found in all animal cells, but are most numerous in disease-fighting cells, such as white blood cells. This is because white blood cells must digest more material than most other types of cells in their quest to battle bacteria, viruses, and other foreign intruders.

lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.

What cells are ribosomes abundant in?

Ribosomes are remarkably abundant in cells. A single actively replicating eukaryotic cell, for example, may contain as many as 10 million ribosomes. In the bacterium Escherichia coli (a prokaryote), ribosomes may number as many as 15,000, constituting as much as one-quarter of the cell’s total mass.

Why do liver cells have lots of mitochondria?

For example, liver cells and muscle cells contain a lot of mitochondria. Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. They need this because of their frequent contraction and relaxation, which requires more ATP than average cells. Amy W.

What is Golgi apparatus do?

A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.

What organelles can you see under a light microscope?

Note: The nucleus, cytoplasm, cell membrane, chloroplasts and cell wall are organelles which can be seen under a light microscope. Under a light microscope, mitochondria are still visible, but thorough research is not feasible.

What organelles can be seen under an electron microscope?

What organelles can be seen under a electron microscope? The cell wall, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes are easily visible in this transmission electron micrograph.

Which organelles would be expected to be prominently represented in the cytosol of a beta cell?

ER and mitochondria are two metabolic organelles playing a key role in beta cell function.

What does the lysosome do?

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

Which of the following cell organelles are involved in the process of detoxification?

The smooth endoplasmic reticulum plays an important role in detoxification of chemicals. This detoxification process occurs in the liver, which contains an abundance of smooth endoplasmic reticulum.

Which organelle removes substances or contains substances brought into the cell?

Lysosomes breakdown/digest macromolecules (carbohydrates, lipids, proteins, and nucleic acids), repair cell membranes, and respond against foreign substances such as bacteria, viruses and other antigens. Lysosomes contain enzymes that break down the macromolecules and foreign invaders.

What substances are detoxified by the liver?

Endogenous substances (or those produced by the body), are also dealt with by the liver. Amino acids are deaminated, some hormones are inactivated, and bilirubin, a product of the breakdown of old red blood cells, is also detoxified and rendered harmless by liver metabolism.

Which organelle helps in formation of lysosomes?

– The formation of lysosomes involves both the endoplasmic reticulum and the golgi apparatus. – Enzymes of the lysosomes are synthesized from the proteins of the rough endoplasmic reticulum.

What is the only cell organelle seen in prokaryotic?

So, the correct answer is Ribosomes.

What are cells that make up most of liver cells?

The most common cells of the liver (making up roughly 90% of the liver’s cells) are called hepatocytes. They are all identical. These cells carry out most of the functions which the liver performs.
