Question

Which of the following is not a function of lysosomes?

1) digesting particles taken in by endocytosis
2) breaking down bone to release calcium ions into the blood
3) are responsible for the synthesis of free radical scavenging system
4) degrading worn-out or nonfunctional organelles
5) forming acid hydrolases which are necessary to help form cell membranes

Answer 1

The function not associated with lysosomes is the synthesis of free radical scavenging systems. Lysosomes are instead responsible for digesting particles, breaking down obsolete organelles, and destroying pathogens among other functions.

Step-by-step explanation:

The function that is not a role of lysosomes is "are responsible for the synthesis of free radical scavenging system". Lysosomes have several key functions such as:

• Digesting particles taken in by endocytosis
• Breaking down bone to release calcium ions into the blood
• Degrading worn-out or nonfunctional organelles
• Contain acid hydrolases necessary for digestion but not specifically for forming cell membranes

Lysosomes, discovered by the Belgian scientist Christian de Duve, are important for maintaining cellular health by recycling cellular waste, using their hydrolytic enzymes to destroy pathogens, and aiding in phagocytosis.
