If an object absorbs all colors but one, we see the color it does not absorb. the answer is red.
Answer:
Let v is the velocity and t is the flight time,then flight relationship fir height is given below.
h=v*t
Answer:
a) to provide NADPH for reductive biosynthesis and for dealing with oxidative stress
d) to provide ribose-phosphate for nucleotide and nucleic acid biosynthesis
Explanation:
During the pentose phosphate pathway, glucose 6-phosphate is oxidized into pentose phosphates. This pathway uses NADP as an electron acceptor and reduces it into NADPH. The products of this pathway, the pentose phosphates are used by the cells to synthesize nucleic acids (DNA and RNA). The pentose phosphates are also used for the synthesis of nucleotides and coenzymes such as NADH, FADH2, etc.
These synthetic pathways are particularly occurring at a higher rate in the rapidly dividing cells such as the cells of bone marrow, skin. The NADPH formed during this pathway is used by cells as an electron donor for the reactions of reductive biosynthesis. Some of these pathways are the synthesis of fatty acids, cholesterol and steroid hormones. NADPH is also involved in scavenging reactive oxygen species such as oxygen radicals. These ROS are responsible for oxidative stress.
Answer:
flux
Explanation:
- The rate by which the turnover of the molecules takes place in a metabolic pathway that regulates the flow of material is termed as metabolic flux or simply flux.
- The various enzymes that are involved in the metabolic pathway are responsible for regulating the flux.
- The flux varies with the different states of activity of a person and it is important for the regulation of metabolic activities as well as maintain the homeostasis of the body.
- The mathematical expression to calculate the flux is :
J = Vf - Vi
Where J = flux of metabolites
Vf = rate of the forward reaction
Vi = rate of the reverse reaction
tRNA brings amino acid molecules to the ribosomes during protein synthesis
