Do does anyone know this​
belka [17]

Answer:

I know that the "ATP" is in the mitochondria which we humans don't have so I would say the first one but I'm not sure but what I've read so far it might be or I'm not sure because u know how the Mitochondria is part of the power houses.

I would think it could also be F because the Mitochondria helps for Cellular respiration and also fermentation.

Explanation:

Therefore the correct answers: B,C, F

So the anwers I believe are with the ones that don't have the Photosynthesis because my explanation here is that animals also have their power houses lol that, that means it's the Mitochondria as well as the plants.

So mitochondria ATP captures energy in Cellular respiration.

Hope this helps u.. ;)
