Answer:

The correct answer would be -

Genotype: IAIO or IBIO

Phenotype: A Blood or B Blood

Explanation:

Blood group A and blood group B both are dominant over the blood group O, however, both A and B are codominant if present together and form the blood group AB.

The blood group of Aman is AB and If he marries the female with O blood group then possible blood group in offspring would be as follows:

gametes: Aman = IA and IB

woman = IO IO

then cross between:

    IA     IB

IO IAIO IBIO

IO IAIO IBIO

the genotype of this cross would be 50% chances of IAIO and 50% chances of IBIO and phenotype would be either Type A or type B.

Energy Metabolism Pathways Carbohydrate metabolism is responsible for the formation, breakdown, and interconversion of carbohydr
Ksivusya [100]

Answer:

The glucose conversion to PYRUVATE opens anaerobic and aerobic metabolic pathways. VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. In the Cori cycle, the release of energy from ATP converts lactate to glucose and returns the glucose molecule to the muscles through the process of Anaerobic Glycolysis.

Explanation:

In metabolism, glycolysis is defined as the splitting of the glucose molecule to form two molecules of pyruvic acid. It is the first main metabolic pathway in cellular respiration for the production of energy in form of ATP(Adenosine triphosphate).

In most cells, cellular respiration occurs in the presence of oxygen. This is known as AEROBIC RESPIRATION which produces the largest number of ATP. Energy can also be gotten by breaking down of glucose in the complete absence of oxygen. This is known as ANAEROBIC RESPIRATION.

The next stage in the degradation of glucose is a two step conversion of the two pyruvic acid molecules from glycolysis into two molecules of acetyl coenzyme A( acetyl - CoA). This occurs in the TCA( tricarboxylic acid) or Krebs cycle.

VITAMIN B NIACIN in its role as a coenzyme during glycolysis, escorts hydrogen and electrons to the electron transport chain and the TCA cycle. Coenzyme A is a derivative of vitamin B which combines with pyruvic acid to form acetyl CoA , 2 molecules of carbon dioxide and 4 molecules of hydrogen in TCA cycle.

In Cori Cycle, (which is also called Lactic acid cycle), energy released from ATP is used to convert lactate to glucose. This is to prevent increased lactic acid in the blood during anaerobic conditions in the muscles.

What makes a water molecule polar? *
Vlad [161]

Answer:

it has partial charges

The hydrogen gives a positive partial charge

The oxygen gives a negative partial charge

Oxygen is way more electronegative than hydrogen therefore the molecule will be polar.
