plz help asap! The activity of many cellular enzymes is regulated by activators and inhibitors. Enzyme activity is also regulated in eukaryotic cells by which of the following mechanisms?

Compartmentalization and restricting enzymes to specific organelles or membranes
Secreting enzymes out of the cell
Limiting the availability of substrates
Changing the primary structure of enzymes

Answers

Answer 1

Answer:

compartmentalization and restricting enzymes to specific organelles or membranes

Answer 2

Cellular steroid gradients are produced by the compartmentalization of enzymes into various organelles of a cell, and this might impact how well the various steroid products are balanced. Thus, option A is correct.

What is Compartmentalization?

In biology, the biomembrane, or biological membrane, effectively compartmentalizes enzymes by allowing them to perform only certain functions within a limited area.

The enzymes may be located on the membrane surface or inside the defined compartments.

A percentage of the enzymes would likely not work or their ability to catalyze reactions would likely be insufficient if there was just one cellular compartment.

This is because enzymes catalyzing distinct reactions frequently have variable temperature and pH optimums.

Therefore, Compartmentalization and restricting enzymes to specific organelles or membranes.

Explain the differences in the three types of RNA by connecting it to a factory.

Answers

[tex] {\huge{\sf{\green{\underline {\underline {Answer }}}}}} [/tex]

Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled .

RNA carries genetic information from the nucleus to ribosomes for the synthesis of proteins; while tRNA carries specific amino acids to the ribosomes to assist the protein biosynthesis, and on the other hand, rRNA provides the structural framework for the formation of ribosomes.

Which of the following is not a stage in hurricane formation?

Thunderstorms in a low-pressure area combined with the Earth’s rotation cause the storm’s initial rotation.

B)

Pollution in the atmosphere raises the temperature of the air, creating a depression.

C)

Warm, moist air rises from the sea and increases the storm’s energy.

D)

As water from the sea turns into water vapor, latent heat enters the storm, causing the storm’s energy to increase.

E)

As condensation (rain) occurs, latent heat is released, which warms the air and makes it lighter, causing the hurricane to increase in strength and intensity.

A biologist reads an article in a scientific journal that describes how the legs

of different organisms look and function differently, but appear to be

constructed from the same basic bones. He compares a drawing of the

skeletal structure of a porpoise's fin with one of an elephant's leg. (7A)

What aspect of the theory of evolution do these drawings support?

Answers

Answer:

Homology

Explanation:

The aspect of the theory of evolution that the drawings support is homology. Homologous organs are organs of different organisms that look similar in structure but perform different functions in reality.

Organs that are built on the same or similar basic plans in the same organisms but perform different functions are thought to have been from the same ancestor. Hence, homology or homologous organ represents one of the evidence used to support the theory of evolution which opines that all living organisms descended with modifications from common ancestors.

Thank you Which of the following describes one of the main obstacles Schwermer's lifestyle presents?Part of that philosophy requires her to put a lot of faith in the unknown. Other than the small notebook she uses to keep track of her scheduled speaking engagements and housing arrangements, most of her plans are left to fate. I see a lot of miracles in my daily life. For example, in the beginning I found food. I thought about things and then I found them in the street or people came to bring them to me, she explains. I think these miracles happen because of our thoughts. When seasons change, she gives away whatever clothing she has and waits for new items to come along. Most are given by hosts and friends she meets along the way. The road wasnt always easy. With two adult children and three grandchildren, Schwermer admits her family wasnt exactly on board when she pitched the idea. She now sees them only a few times per year, but says they eventually warmed up to her come-and-go lifestyle. Now theyre proud of what Im doing. Its enough for us, she says. Although she never had plans to go public with her life, after a German book publisher pushed her to put pen to paper, Schwermer relented. The latest of three books on her journey, Seeing Miracles In Life Without Money, will be released this summer in Germany. As with its predecessors, all her royalties4 will go to the various charitable groups she supports. Now, more and more young people want to change something in their lives and often they dont know what they can change, she says. I changed something in my life. Despite the legion of fans that have followed her for years, Schwermer has met her fair share of critics. After a trainwreck appearance on Italian talk show RAI TV, she stopped doing television interviews (in one taping, a host actually rifled through her suitcase).More often than not, however, its her friends who become frustrated with her come-and-go lifestyle. Shes turned down many invitations to extend her visits, including offers to stay permanently. There are so many people who are lonely and they like to have friends at their side, she says. But I say no because I cant. I feel that I must go.
