Answer:
The correct answer is option A.
Explanation:
Cell cycle checkpoints are regulating mechanism that ensures the presence and viability of the cellular components essential for cell division.
There are three major checkpoints one G1 second at M phase and third is G2 checkpoint. M phase checkpoint ensures for chromosome spindle attachment. G1 checkpoint checks the nutrients, DNA damage and growth.
Thus, the correct answer is option A.
Answer:
The correct answer is d Lysosomes contain enzymes to breakdown damaged cellular material.
Explanation:
Lysosomes are called digestive organelle that contain many hydrolytic enzymes such as acid hydrolase ,peptidase, nuclease etc which aids in the digestion of various cellular components such as carbohydrates,protein,nucleic acid.
Lysosome perform the same function by the formation of auto phagolysosome which contain the those cellular molecules and organelles those are targeted for degradation.
Hydrogen and oxygen make up water for polar molecules. And it is neutral
Answer:
Explanation:
adj. Moving or operating in one direction only: a unidirectional microphone.
Some organelles that we can mention are endoplasmic reticulum, lysosomes, cytoskeleton, peroxisomes, and nucleus.
<h3>What is the function of the organelle called mitochondria?</h3>
The function of mitochondria to generate energy occurs through the process known as cellular respiration. The process consists of oxidizing molecules - usually derived from glucose present in the cytoplasm - and converting the energy generated from this oxidation to form energy-carrying molecules such as ATP.
In this case, the main cell organelles and their functions are of these organelles in the processes is:
- Mitochondria : respiration
- Ribosomes: amino acid binding
- Endoplasmic reticulum; protein production
- Golgi Complex: storage
- Lysosomes: digestion
- Peroxisomes: oxidation
- Vacuoles: reserves and Plasts
