Natalka [10]

Answer:

22. C

23. C

24. Not clear, maybe 18%

25. Left ventricle, because according to the graph nearly 50% of the organ contains mitochondria, more than the left atrium.

Explanation:

22. Active transport requires cell's energy to move molecules, usually in the form of ATP.

23. This is a trick question, you might think it is diffusion or osmosis, but is is exocytosis. Diffusion and osmosis don't require vesicles for transport. It isn't endocytosis, because that is moving molecules inside the cell. The question asks for moving out the cell.

24. Look at the chart, it is less than 20, but more than 10 and more than halfway. I am not sure exactly the percentage, I would approximate it to be 18%.

25. Most likely left ventricle.

please give thanks :)

The immediate energy system (ATP-PC) relies on:
swat32

Answer:

c. the high-energy phosphates stored in muscle cells

Explanation:

Phosphocreatine (PC) or creatine phosphate is a compound rich in energy. It has energy stored in it which can be used to phosphorylate ADP into ATP. The phosphocreatine is stored in muscle cells when muscles are not working. The produced ATP serves as an energy source for muscle contraction. The creatine produced during ATP production is phosphorylated again into PC using ATP when muscles are resting.
