Ans.
An electron carrier is defined as a molecule, which is capable of receiving one or more electrons from an electron donating molecule (electron donor). In given figure, molecule NADP (nicotinamide adenine dinucleotide phosphate) is acting as an electron carrier that accepts electrons form chlorophylls and form NADPH.
Thus, the correct answer is 'option C). NADP.'
Answer:
Nucleic acids
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleic acids found in the nuclei of living cells. They are the vehicles of genetic inheritance.
Nucleic acids are condensation polymers of nucleotides. To understand their functions you will find it helpful to look at how their molecules are built up and the structures of these molecules.
Explanation:
Waste (byproducts) made by the cell that serves no purpose to keep inside the cell membrane.
The organism that has all the adaptations listed above is C. polar bear.
Answer:
B. The amount of unbound cyclin E is lowest as the cell enters S.
Explanation:
The reproduction of the cell is a cycle that it regulates by itself, depending the demand of a certain cell.
In the case of the mitosis, in Each change from G1 to S to G2 to M is regulated by some proteins like the cyclin.
In the case of the cdK2 is ncessary to pass the control point to pass from the stage G1 to the stage S.
Another characteristic of the cyclins, is that these proteins are synthetized and degraded constantly during the hole process.
