D) Oxygen is NOT Needed. That is something that will come out of it. After photosynthesis, Oxygen comes out of it. It is  kind of a side effect. They give out oxygen, we breath out Carbon Dioxide.

Living cells cannot use heat to provide the activation energy for biochemical reactions because ________. Which choice(s) comple
postnew [5]

Considering the following;

I. Heat is not readily available to all living cells.

II. Heat at excessive amounts denatures proteins.

III. Heat does not provide the activation energy for their reactions.

IV. When a critical temperature is reached, proteins no longer function

Answer;

I and IV

Explanation;

Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.

Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.

Consider a cell that requires much more ribose5‑phosphate than NADPH. The cell needs ribose 5‑phosphate but has a relatively hig
Sergio039 [100]

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.
