What releases energy in a cell?

Question

There is some structure that does. Like how the ribosomes make portein, or the nucleus directs cell activities. Please help me. I was gone from school for about 2 weeks and they learned all thsi stuff when I was gone. And I have to do this catch-up work, learn the stuff at the same time, and take a test on it in 2 days. : (. Thanks a lot.

Answer 1

ATP releases energy in a cell.

Answer 2

Mitochondria is a cell organelle which releases energy into the cell.It is also called the power house of the cell.The energy which is released from the mitochondria is stored in the cell when it is unused in the form of ATP or adenosine triphosphate and when the ATP loses energy it becomes ADP or adenosine diphosphate , when the ADP gains energy again, then it will turn into the ATP which is a ready to use energy unit of the cell. Mitochondria functions when the food or any kind of food is absorbed into the cell , the mitochondria oxidizes the food to to obtain heat energy which makes its molecules vibrate more like the matter and with that energy the cell can perform their life activities and function properly. The function of the mitochondria therefore is a chain reaction.

Answer 3

The Mitochodria

Mitochondria provide the energy a cell needs to move, divide, produce secretory products, contract - in short, they are the power centers of the cell. They are about the size of bacteria but may have different shapes depending on the cell type.

Mitochondria are membrane-bound organelles, and like the nucleus have a double membrane. The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds called cristae. The cristae greatly increase the inner membrane's surface area. It is on these cristae that food (sugar) is combined with oxygen to produce ATP - the primary energy source for the cell.

Answer 4

Well, the energy is made available by the mitochondria. Those organelles will take in sugar, and use it to convert adenosine diphosphate (ADP) into adenosine triphosphate (ATP). ATP is the "fuel" that the rest of the cell runs on, by downgrading ATP to ADP again.
Read the links, perhaps this will bridge the gap of the missing two weeks. Good luck.

Answer 5

Well the part of the cell that produces energy is the mitchondria so basically just study it.

Answer 6

mitochondria

Memory trick:
A cell has to have energy from the mitochondria to be "mighty".

Answer 7

Try reading the book. Perhaps the answer is in there!

Answer 8

I suppose the ATP molecules..
