In glycolysis, if glucose is labeled at the carbon 6 position (see page 1 for numbering of carbons in glucose) A) the carbon wit
Oliga [24]

Answer:

D) the carbon with the low-energy phosphate on it in 1,3 BPG is labeled.

Explanation:

Glycolysis has 2 phase (1) preparatory phase (2) pay-off phase.

<u>(1) Preparatory phase</u>

During preparatory phase glucose is converted into fructose-1,6-bisphosphate. Till this time the carbon numbering remains the same i.e. if we will label carbon at 6th position of glucose, its position will remian the same in fructose-1,6-bisphosphate that means the labeled carbon will still remain at 6th position.

When fructose-1,6-bisphosphate is further catalyzed with the help of enzyme aldolase it is cleaved into two 3 carbon intermediates which are glyceraldehyde 3-phosphate (GAP) and dihyroxyacetone  phosphate (DHAP).  In this conversion, the first three carbons of fructose-1,6-bisphosphate become carbons of DHAP while the last three carbons of fructose-1,6-bisphosphate will become carbons of GAP. It simply means that GAP will acquire the last carbon of fructose-1,6-bisphosphate which is labeled. Now the last carbon of GAP which has phosphate will be labeled.  

<u>(2) Pay-off phase</u>

During this phase, GAP is dehydrogenated into 1,3-bisphosphoglycerate (BPG) with the help of enzyme glyceraldehyde 3-phosphate dehydrogenase. This oxidation is coupled to phosphorylation of C1 of GAP and this is the reason why 1,3-bisphosphoglycerate has phosphates at 2 positions i.e. at position 1 in which phosphate is newly added and position 3rd which already had labeled carbon.

It is pertinent to mention here that<u> BPG has a mixed anhydride and the bond at C1 is a very high energy bond.</u> In the next step, this high energy bond is hydrolyzed into a carboxylic acid with the help of enzyme phosphoglycerate kinase and the final product is 3-phosphoglycerate. Hence, the carbon with low energy phosphate i.e. the carbon at 3rd position remains labeled.

Yakvenalex [24]

The density of the solid is  6.724 g/ml.

Density is the number of factors which can be people, animals, vegetation, or objects in a sure place. To calculate density, you divide the number of objects by the dimension of the place. The populace density of a rustic is the wide variety of human beings in that us of a divided by means of the location in square kilometers or miles.

The density of an amount to being counted is its mass divided by means of its quantity. it also includes measured at zero °C and at 1 atmosphere of stress. Density is vital in figuring out the buoyancy of materials in fluids, as well as in evaluating materials and other measurements.

The density of an object is certainly one of its maximum crucial and easily-measured physical properties. Densities are extensively used to perceive natural substances and to represent and estimate the composition of many varieties of combos.

density = mass/ volume

      = 975g/145ml

      = 6.724 g/ml

Which part of chromosomes passes in trait from parent to offspring
AfilCa [17]

Answer:

Genes

Explanation:

The genes are the basic unit of hereditary which are a part of chromosomes that are passed from parents to their offspring.

Genes are responsible for the propagation of hereditary features. They are usually located on the chromosome.

Genes are made up of protein molecules.

Each parent passes down a copy of their gene which are inherited by the offspring and they determine a character state.

They generally make up the genotype.
