Energy coupling is the transfer of energy from the energy forming step to the biomolecule forming step. The energy forming step is called catabolism wherein the complex molecules are broken down and releasing energy. The energy produced is then used the process called anabolism which produces biomolecules such as proteins.
This is a cellular respiration question, related to biology.
Some processes in our bodies require the use oxygen, others do not.
In this case, the conversion of pyruvic acid to acetyl co-enzyme A and the production of water in the electron transport chain do require oxygen.
If oxygen was not present for pyruvate, it would turn into lactic acid via fermentation. Water in the ETC is formed in the process when NADH and FADH2 are converted to molecular oxygen due to the electron transporters. The protons are then pumped and oxygen is reduced to form H2O.
Answer:
sulfur oxide and nitrogen oxide
Explanation:
these are released from power plants along with carbon dioxide
Answer:
Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds. Vestigial structures can become detrimental, but in most cases these structures are harmless; however, these structures, like any other structure, require extra energy and are at risk for disease.
