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:
the drive-reduction theory
Explanation:
The drive-reduction theory is one of the theories of motivation.
This theory contains the idea that a physiological need creates a drive, which in turn motivates an organism to satisy their need.
The theory targets homeostasis or biological balance.
When there is a need such as lack of water, the need would cause a drive to be developed (thirst).
The drive would activate a response (search for water to drink).
The response is then terminated when the need has been satisfied.
Answer:
Deoxyribose and phosphate
Explanation:
The other molecule of the sides that lies in between sugar are deoxyribose and phosphate. The sugar has the nitrogenous based molecule attached to it.
Answer:
A. Organ
Explanation:
Leaf is an essential part of plant that is involved in photosynthesis and also in exchange of gases. It is made up of epidermis, which is thick one, and is present at lower and upper surface of leaf. Between upper and lower epidermis, mesophyll is present while cuticle is present outside of the epidermis. Xylem and phloem and other connective tissues are arranged in the leaf in such way that it maintains the shape as well as effective transfer of nutrients and water in the leaf. Leaf is an organ, made up of all these tissues to form a complex structure.
