Answer:
The ATP synthase can be thought of as a type of molecule motor that is powered by the flow of __H+_ through the subunits and __down_ their concentration gradient.
Explanation:
There are two steps for the synthesis of carbohydrates in plants; one is light reaction and other is dark reaction. In light reaction the ATP and NADPH are produced from sunlight and these molecules are utilized for combining the carbon molecules in dark reaction.
Before we discuss chemiosmosis (Mechanism of ATP production) we should know that light reaction takes place in the thylakoid membrane of chloroplast. During the light reaction electrons removed from water are excited by light in photosystem I and photosystem II. These excited electron release the energy while traveling down the electron transport chain which is utilized to pump the H+ ions to stroma from lumen. This build a concentration difference of H+ ions across the membrane.
So when these H+ ions flow from stroma to lumen i.e. higher potential to lower potential they passes through ATP synthase complex. ATP synthase produces the ATP by the phosphorylation of ADP that why mechanism is also referred as Photophosphorylation.
Answer:
Each homologous chromosome in a pair is from a different parent. First-division nondisjunction will only yield gametes with an extra chromosome, whereas second-division nondisjunction will only yield gametes missing a chromosome.
Explanation:
Non-disjunction occurs when a the chromosomes do not split properly during meiosis resulting in too few chromosomes I believe.
The polymerase chain reaction makes DNA fingerprinting more reliable because it allows scientists to quickly make many copies of DNA the answer is C
Answer:
Yes, the protein is found on the surface of the red blood cell which is represented by a positive or negative sign.
It is termed as Rh factor.
Rh factor refers to the class of antigen or protein found on the red blood cell.
If the protein is present, then the person is said to be Rh positive and when the protein is absent the person is said to be Rh negative.
