Answer:
Oxidation of NADH by electron transport chain ensures a continuous supply of NAD+ for glycolysis.
Explanation:
To continue the process of glycolysis, cells must have a continuous supply of NAD+ which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.
Answer: D) located in the lysosomes
Answer:
Semi-conservative
Explanation:
Meselson–Stahl experiment proved that DNA replication is a semiconservative process, feeding E. colo bacteria with different types of Nitrogen isotopes (N14 and N15).
Changing the type of radioactive compound in different times of bacteria grow, they could observe that both of the isotopes were present on the bacteria culture.
Basically, if the bacteria present both of them, the DNA was replicated semiconcervely.
Guess what? they show both! (See the image for more information)
Answer:
The correct answer is B respiratory system
Explanation:
Respiratory system of our body play a significant role in the inhalation of oxygen into and exhalation of the waste product known as carbon dioxide from our body.
Respiratory system basically composed of diaphragm and respiratory muscles.The volume of diaphragm increases during inhalation and decreases during exhalation. This is called the elastic nature of lungs which helps in efficient gas exchange.
