Help please, thank yous :'D 1. Why would cells in some organs be consuming more oxygen than cells in other organs?
2. What happens to the glucose levels in the blood after a meal? Why does this happen?
3. Why might our muscles “burn” when we exercise for long periods of time?

1- Im not sure, im so sorry! I hope i could help, if I have the answer ill edit this :)

2- When you eat some form of carbohydrate, the body breaks it down into glucose, such as pasta, fruit, bread or sugar. Glucose is absorbed into the bloodstream and, to be used for energy, insulin helps extract it from your blood into your cells.

3- The breakdown of molecules for energy occurs in the muscle region as people work out, which is why people may feel their muscles burning at the end of a difficult workout.

Intro:

Hello!!! Princess Sakura here ^^

Explanation:

1.) Every cell in your body needs oxygen for cellular respiration. Cellular respiration uses oxygen to break down sugar and create energy. The mitochondria are organelles that produce ATP and usually the muscle cells need the most because they are always working.

2.) The carbs you consume converts to blood sugar. So the more carbs you ingest the higher the levels of glucose you'll have released.

3.) It's because as we workout the breakout of molecules for energy happens in the muscle area, and that's because muscles have the most energy and needs the most energy.

the correct answer is 2 and 4
