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.

how does water move through the water cycle

Answers

Answer: The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, runoff, and subsurface flow. In doing so, the water goes through different phases: liquid, solid (ice), and gas (vapor).

Transcription is the process that must happen in order to make

Answers

Answer:

a protein

Explanation:

Transcription is one of the three main, necessary events needed for proteins to form in a cell. This happens when DNA is transcribed to mRNA. Thymine (T) is subbed in by Uracil (U), so when transcribing, A's turn into U's, not T's.

Transcription is the first step of gene expression. During this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed. The region of opened-up DNA is called a transcription bubble.

Which of the following best describes the genes of offspring of organisms that reproduce sexually?

Answers

Answer:

Each of the offspring is genetically unique and received some of its genetic

Explanation:

While reproducing sexually, The zygote receives half of the gametes of male organism while half of the gametes of female organism. This constitutes to the total number i.e. 46 chromosomes.

While the zygote receive half from male and half from female, This means that the offspring produced by the zygote will have both the characteristics in common of the male as well as female. Remember that, Chromosomes contain gene which are particularly responsible for characteristics.

So, Each of the offspring is genetically unique and received some of its genetic  information from each parent, so each has some traits in common with each parent.
