D12 lysosomes

Question 1

How are lysosomes formed?

Answer 1

When small pieces of the golgi body are pinched off at the end?

Question 2

What is the structure of a lysosome?

Answer 2

Small, temporary vacuoles, surrounded by a single membrane, which contains and isolates the hydrolytic digestive enzymes from the rest of the cell

Question 3

What are the functions of a lysosome?

4

Answer 3

1. The Lysosome releases hydorolytic digestive enzymes when the cell needs to recycle worn out organelles
2. The Lysosome also releases these digestive hydrolytic enzymes when it wants to digest for example bacteria taken into a white blood cell via phagocytosis
3. Lysosomes can release Lysozymes outside of the cell to digest other cells, (Exocytosis)
4. Lysosomes can also force the cell to self destruct - Autolysis

Question 4

How do lysozymes prevents these enzymes from digesting the cell itself?

Answer 4

Small, temporary vacuoles, surrounded by a single membrane, contains and isolates the digestive hydrolytic enzymes from the rest of the cell
