Answer:

a. the RNA polymerase undergoes abortive initiation prior to promoter clearance

Explanation:

In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.

In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.

Most bacterial RNA transcripts do not undergo splicing.

The nucleosome is the basic unit of chromatin repeat in eukaryotes.

why is sustainable use of natural resources important? to ensure that natural resources are available for future generations to
zlopas [31]

Answer:

The correct answer is (a) to ensure that natural resources are available for future generations.

Sustainable development means optimized use of natural resources to meet the demand of people in the present and future scenario. The main aim of sustainable development is to balance our economic, environmental and social needs which allows the prosperity for now and future generations. Sustainability can only be maintained when the resources are used in a way that it meets the need of people, not the greed of people.This is done to ensure that natural resources are available for future generations.

Explanation:

Hope this helps...

During periods of intense activity, when glycolysis is used in the generation of atp, the reaction lies to the right, decreasing
umka21 [38]

Adenosine monophosphate (AMP) is a regulatory molecule in metabolic processes such as glycolysis and gluconeogenesis. For example, it stimulates the glycolytic enzyme phosphofructokinase, and therefore ATP production, and it inhibits the gluconeogenic enzyme fructose 1,6-bisphosphatase. Adenylate kinase catalyzes the reversible reaction shown here:


2ADP --> ATP + AMP


During periods of intense activity, when glycolysis is used in the generation of ATP, the reaction lies to the right, decreasing [ADP], generating ATP, and accumulating AMP. However, [ATP] is usually much greater than [ADP], and [ADP] is greater than [AMP].


Determine [AMP] when 3% of the ATP in a hypothetical cell is hydrolyzed to ADP.


<span>In this cell, the initial concentration of ATP is 265 ?M, and the total adenine nucleotide concentration (the concentration of ATP, ADP, and AMP) is 368 ?M. The equilibrium constant K is 0.82</span>

the salivary glands, stomach, and pancreas secrete ____________ enzymes to break down triglycerides into monoglycerides, fatty a
likoan [24]

The salivary glands, stomach, and pancreas secrete<u> lipase enzymes</u> to break down triglycerides into monoglycerides, fatty acids, and glycerol.

Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.

That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.

<u>About lipase enzymes</u>:

  • It acts on the neutral fats in the diet, splitting them into triglycerides or diglycerides and these to monoglyceride, which is the most easily absorbed fatty compound.

  • The action of lipase is much more manifest on triglyceride, and it is also much faster the higher the molecular weight of the fatty acid present.

  • It acts on the surface and in an aqueous medium, the emulsifying agent represented by bile salts is essential for optimum effectiveness.

  • They are widely distributed, with a presence in the animal and plant kingdoms and even in the simplest unicellular organisms.

Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.
