The role of oxygen in cellular respiration is to (d) act as the final electron acceptor. Oxygen is used in all main steps of the cellular respiration; in glycolysis, citric acid cycle, and oxidative phosphorylation. It attracts so much electrons more than any other proteins.

c. allow glycolysis to continue.

The reactions that are catalysed by enzymes actually helps the organism to grow, respond to various changes in the environment, reproduce and continue maintaining their own structures. Cellular respiration is also considered a part of the metabolism process. This process actually helps in carrying the oxygen through the blood.

Answer from: Quest

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

Answer from: Quest

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
