C. is essential in the synthesis of dna and in the development of red blood cells.
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:
O blood is a recessive trait, so none of the children will have O blood. The genes for either type A or Type B will be determined by the egg/sperm being fertilized with the reproductive cell of the other parent. the probability of receiving either of the gene versions is 1/2, so half of the children will have A blood and the other half will have B blood
Answer:
B
Explanation:
Oxygen is the final acceptor of electrons in the process of oxidative phosphorylation. Without oxygen, the process becomes jammed with electrons.
The correct answer in this question is letter B. Taste buds that are located at the tongue recognize some dissolved chemicals from the food for taste perception. Examples are hydrogen ions giving off sour taste, carbohydrates for sweet taste, magnesium ions give off bitter taste, sodium ions for salty taste and monosodium glutamate for umami taste.
