Answer: The correct answer is option b
Explanation:
It is the reaction of cellular respiration in which glucose is oxidized to produce energy (ATP). Carbon dioxide and water are produced as byproducts.
It is the reaction which produces energy for all other cellular functions. One molecule of glucose yields around 36-38 ATP molecules.
Rest other reactions such formation of ATP (ADP + P = ATP) gets energy from chemiosmosis produced by cellular respiration. Formation of sugars from carbon dioxide and water (option c) gets energy from solar energy (photolysis). Formation of proteins (amino acids to proteins) or translation is also an energy-driven process. It gets energy from hydrolysis of ATP.
Thus, the correct answer is option b.
Answer:
The proximal convoluted tubule.
Explanation:
Diffusion is a process that occurs when a substance such as water, molecules, and ions, which are usually needed for various cellular processes, enter and leave cells. The way that cell diffusion happens is by molecules moving from an area of high concentration to an area of low concentration.
The characteristic feature of the semi-conservative replication of DNA is formation of the leading strand and the lagging strand. DNA polymerases are the enzymes that can add nucleotides to the 3 ' end of the DNA strand only. A DNA double helix is anti-parallel in which one strand runs from 5 ' to 3 ' and the other from 3 ' to 5 ' direction. On the strand having a primer with a 3 ' end, the synthesis of DNA is continuous and forms the leading strand. On the other strand, DNA fragments called Okazaki fragments are produced with multiple RNA primers. It is called the lagging strand. The enzyme DNA ligase joins these Okazaki fragments on the lagging strand. Thus, any defect in the enzyme will affect the lagging strand only and not the leading strand as it does not have any Okazaki fragments.
