Answer:
Water
Explanation:
Molecular oxygen is the terminal electron acceptor and serves to receive electrons from reduced NADH and FADH2 to reoxidize them. NADH and FADH2 are formed during glycolysis and Kreb's cycle. These reducing powers should be re-oxidized to enter in the first two steps of aerobic respiration again.
For the purpose, NADH, and FADH2 transfer their electrons to the molecular oxygen via electron transport chain. After accepting the electrons, molecular oxygen is oxidized into the water molecule. Therefore, radioactive oxygen isotope would appear in the form of a water molecule after completion of cellular respiration.
The answer is D, All living things are made up of cells.
Answer:
b. Mutations that inactivate tumor suppressor genes are important in cancer.
Explanation:
Most cancers have inactivating mutations in one or more proteins that normally,Cancer can result from expression of mutant forms of these proteins: growth factors and mutation in only one of the two alleles is sufficient for induction of cancer, the cells from tumors caused by these viruses is near the c-myc gene.
