How would you describe a key difference in the functions of lysosomes and peroxisomes ?

Answers

Lysosomes and peroxisomes both contain enzymes and are membrance bound organelles. The difference between the two are their functions, because lysosomes digest material like bacteria and also digest its dead organelles and AIDS in apoptosis, while peroxisomes aid in liquid metabolism and chemical detoxification.

Lysosomes contain different hydrolytic enzymes, that is, digestive enzymes, related to the intracellular digestion process, while peroxisomes are organelles that carry out oxidative reactions.

What are lysosomes?

Lysosomes are organelles that belong to the endomembrane system, defined as the group of membranes and organelles of eukaryotic cells and contain enzymes that are involved in the process of intracellular digestion.

What are peroxisomes?

Peroxisomes are cytoplasmic organelles found in most eukaryotic cells that harbor various oxidative enzymes such as peroxidase and catalase.

Differences in the functions of lysosomes and peroxisomes

Lysosomes house the molecules responsible for the degradation of intracellular material of both internal and external origin.

The oxidation of amino acids and fatty acids is part of the functions of peroxisomes, they are also responsible for catabolizing purines and eliminating hydrogen peroxide.

Therefore, we can conclude that the main function of lysosomes is to digest substances, both external and internal to the cell, while peroxisomes are organelles that house oxidative enzymes to carry out oxidative reactions.

What's the first thing you should do if you find yourself involved in a conflict?

Answers

Answer:

The first thing to do is to calm down.

Explanation:

In a conflict it's important to remain calm, take responsibility, and breathe, then from there you can calmly negotiate with ease

Answer:

I agree with the other person, the first thing you should do is just calm down. Take a deep breath, and pray to God to help you keep your cool, and not get too upset. Next, I'd say try to think where the other person is coming from. We all have different perspectives of things. Take a minute to listen what the person (or people) have to say. Third, Once they are done talking, try to explain your side of the situation, just remember to stay calm, and not see angry or upset (don't have a mad tone to your voice.) Try to be nice, and compromise with the other person (or people.) The end! Hope it helps! God bless!

Answers

Elevating the affected limb eases the pain.

It’s best not to apply ice packs directly to the skin, but the area around the injury, you SHOULD ice it for 20 minutes but not necessarily every 2 hours, just do it 4-8 times a day, compression is effective for up to a week, but elevation reduces pain level if you keep it above heart level.
