Answer:
"One gene-one protein" hypothesis states that one gene codes for one protein while the "one gene-one polypeptide" hypothesis states that one gene codes for one polypeptide chain of a protein having more than one type of polypeptide chains.
Explanation:
Beadle and Tatum proposed the one gene-one protein concept to explain the one-to-one correspondence between genes and proteins. Accordingly, one gene carries information to encode one protein. Since enzymes are proteins with catalytic power, a gene encodes the information to produce a single enzyme.
The "one gene-one protein" concept was later modified into the "one gene-one polypeptide" hypothesis. According to the "one gene-one polypeptide" hypothesis, one protein may have more than one polypeptide chain. One gene carries the genetic information to encode one polypeptide. Therefore, a protein with more than one type of polypeptide chains will be encoded by more than one gene.
The activity of Rubisco activase can be regulated by the ADP/ATP ratio in the stroma because ADP inhibits the ATP hydrolysis reaction of the activase, which is required to remove the inhibitors.
They are at the beginning because they absorb the energy from the sun and the energy or the sun gets transferred by each organisms
In converting a number with the unit of meter into kilometer we must use the conversion factor 1 km per 1000 meters.This is because in 1 kilometer there are 1000 meters and then the unit to be converted is already in meter so we need to divide it for us to convert.
