The right answer is C
This process is called anaerobic respiration. It doesn't need dioxygen to occur (it can happen with or without O2).
Anaerobic respiration is a mechanism in which electrons pass through a chain of transporters whose final acceptor is a mineral substance other than oxygen, unlike aerobic respiration where the final acceptor is dioxygen. The final acceptor may be the nitrate ion (as in the case of Pseudomonas), carbon dioxyde or the sulfate ion.
Some bacteria (Pseudomonas) are able, anaerobically, to reduce nitrates to nitrites and then, depending on the case, to dinitrogen (with the enzyme Nitrate reductase A).
NO3- ==> NO2- ==> N2.
Answer:the main use of lipids is to store energy
Explanation:If we eat a lot of food, we don't really need all of the energy that we get from it. So, our body stores it away for when we need it later. Hope this helps!
The third one is incorrect.
A plant releases oxygen during photosynthesis not carbon dioxide.
Hope this helps.
I know carbon dioxide is, I don’t think oxygen and water vapour are. I don’t know the others, sorry
The overall three-dimensional structure of a polypeptide is called its tertiary structure. The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein.
