Question

Dude why is bio so hard please help lol

During cellular respiration, glucose molecules undergo a series of reactions. This process results in the formation of up to 38 molecules of high-energy ATP per each molecule of glucose. Which is the source of the energy stored in these ATP molecules?

chemical energy originally stored in the glucose molecule

potential energy from the difference in the concentration gradients of the cell

kinetic energy generated by the chemical reactions

electric current created during the destruction of electrons in the glucose

Answer 1

A. Chemical energy originally stored in the glucose molecule.

Step-by-step explanation:

Lol, I feel you. Bio can be a pain, confusing and tricky sometimes.

Answer 2

1.Sugar bonds

2.Transport proteins

3. Digestion

4. Oxidation

explanation

Chemical energy is stored in the bonds of sugar.

The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.

Digestion converts chemical energy into kinetic energy used by cells.

When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.

Not 100% sure whether it's the correct answer but the concept is true 100% btw I stand to be corrected
