Explanation:

The options attached to this question are as follows:

A.a classroom compound microscope

B.a transmission electron microscope

C.a scanning electron microscope

D.a scanning tunneling microscope.

Scanning electron microscope is a form of electron microscope that has the capacity to produced the image of a viewed substance by scanning the surface of the sample with a strong beam of focused electrons.

Why is feedback inhibition important in metabolic pathways?
GrogVix [38]

Answer:

To balance the production of certain products.

Explanation:

Feedback inhibition is when byproduct from metabolic reactions in cells accumulates and is in excess. The product goes and inhibits the enzyme that is responsible for speeding its chemical reaction, balancing the amount of product needed, with the amount already produced.

Therefore feedback inhibition is important in metabolic pathways because it balances the production of amino acids and nucleotides. It is there to ensure that the exact amount needed is produced.

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.
