Consider a cell that requires much more ribose5‑phosphate than NADPH. The cell needs ribose 5‑phosphate but has a relatively hig

h concentration of NADPH and a low concentration of NADP+. These conditions may occur in rapidly dividing cells. What is the fate of glucose 6‑phosphate, glycolytic intermediates, and pentose phosphate pathway intermediates in this cell?

Answer:

The fate of glucose-6-phosphate,glycolytic intermediates and pentose phosphate pathways are described below

Explanation:

Fate of Glucose -6-phosphate

Glucose-6-phosphate undergo dephosphorylation to form glucose when there is an increase demand of glucose in the body.

Glucose-6-phosphate enters into pentose phosphate pathway to synthesize ribose-5-phosphate which is used during denovo pathway of purine nucleotide biosynthesis.

Fate of glycolytic intermediates

Glyceraldehyde-3-phosphate is an important intermediate of glycolysis.The glyceraldehyde-3-phosphate act as a precursor during lipogenesis that deals with the biosynthesis of triacylglycerol.

Fate of pentose phosphate pathway intermediates

Ribose-5-phosphate and NADPH are the important intermediates of pentone phosphate pathway.

 Ribose-5-phosphate act as a substrate molecule during the denovo biosynthesis pathway of purine nucleotides.

NADPH act as a reducing agent during fatty acid biosynthesis process.

Crossing over occurs during Prophase II.<br><br> A. True<br><br> B. False
Lemur [1.5K]
False
crossing over occurs in prophase 1 of meiosis 1. The significance of this crossing over is to ensure cell differentiation. If this occurred in prophase two it means the cells in meiosis 1 will be identical.

The length and complexity of a food web in the Arctic would be ____ when compared to one in the tropical rainforest.
Vlad [161]

Answer:

The correct answer is - option A. short and less complex.

Explanation:

A food web is a network of many food chains. The food chain is one pathway that describes the path of the animals finds food, it is linear representation. Food web shows all the plants and animals in connection with each other in the food web.

In the Arctic, biodiversity is comparatively low with fewer species of flora and very less number of fauna that include caribou, hare, musk ox pika, and insects are the primary consumers.

Secondary consumer eats herbivores and these organisms are normally are top trophic levels in arctic include fish and polar bear. So the consumers, primary consumer and predators or secondary consumers form a short and less complex.

Thus, the correct answer is - option A. short and less complex.
