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:
sea water contains a salt
Answer:
The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
Explanation:
Answer:
Solar energy can be used
Explanation:
Solar energy can be regarded as a radiant light and heat, it is an energy that is gotten from the Sun which is been trapped with the help of
range of ever-evolving technologies. This technologies could be photovoltaics as well as solar heating, and solar thermal energy. Solar energy is gotten from the sun and is been converted to "thermal energy" or "electrical energy". It's one of most abundant source of renewable energy with minimal impact on the environment. It is a very safe form of energy since it doesn't release CO2 or carbon monoxide to the atmosphere like coal power plant
