Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The lysosomes breaks down waste which is called ____ and then it gets rid of the broken down materials which is called ____
A
digestion, cellular respiration
B
excretion, digestion
C
digestion, excretion
D
cellular respiration, excretion
Explanation: 

Detailed explanation-1: -In addition to being able to break down polymers, lysosomes are capable of fusing with other organelles & digesting large structures or cellular debris; through cooperation with phagosomes, they are able to conduct autophagy, clearing out damaged structures.

Detailed explanation-2: -Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers-proteins, nucleic acids, carbohydrates, and lipids.

Detailed explanation-3: -Lysosomes break down macromolecules into their constituent parts, which are then recycled. These membrane-bound organelles contain a variety of enzymes called hydrolases that can digest proteins, nucleic acids, lipids, and complex sugars.

Detailed explanation-4: -As most high schoolers learn, the lysosome carries out waste disposal and recycling. In a process known as autophagy (meaning “self-eating”), it takes in old cellular components and unneeded large molecules, such as proteins, nucleic acids and sugars, and digests them with the help of enzymes and acids.

Detailed explanation-5: -Lysosomes. The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused.
