Molecule "M" is a second messenger, whose lifespan in cells is 1 min. After stimulation of a cell surface receptor, production o

f M is reduced ten-fold. A decrease in concentration of M is required to mediate an increase in the activity of enzyme "E". What best describes the effect on this signaling pathway if the lifespan of "M" was suddenly changed to 100 min? A.Activity E will decrease more slowly B.Activity E will increase more slowly. C.There will be no significant effect. D.Activity E will decrease more rapidly.E. Activity E will increase more rapidly

<h2>The correct option is (B)</h2>

Explanation:

  • Enzymes are proteins that essentially accelerate the pace of for all intents and purposes the entirety of the substance responses that occur inside cells. They are indispensable forever and serve a wide scope of significant capacities in the body, For example, helping in processing and digestion.  
  • Proteins play out the basic assignment of bringing down a response's enactment vitality—that is, the measure of vitality that must be placed in for the response to start. Enzymes work by authoritative to reactant atoms and holding them so that the substance bond-breaking and bond-shaping procedures happen all the more promptly.

Consider the following geometric solids a sphere with a ratio of surface area to volume equal to 0.08 M negative one a right cir
azamat

Options:

A. The rate of diffusion would be the same for the two models.

B. The rate of diffusion would be faster for the right cylinder.

C. The rate of diffusion would be slower for the right cylinder.

D. The rate of diffusion would be faster for the sphere.

Answers:

The rate of diffusion would be faster for the right cylinder. Thus, the correct option is B.

To begin with, we must comprehend how the ratio of surface area to volume affects the rate of diffusion.

When comparing the ratio of surface area to volume, a body with a larger surface area will have a higher rate of diffusion than a body with a smaller surface area. It can be expressed mathematically as:

V∝ R    (whereas v is the diffusion rate and r is the surface area to volume ratio)

The answer to the question's surface area to volume ratio for spheres is given 0.8m⁻1

For a right circular cylinder, the surface area to volume ratio is provided  is 2.1 M.

The right circular cylinder has a larger ratio, hence it is obvious that the right circular cylinder will have a higher rate of diffusion because the rate of diffusion is directly related to the surface area to volume ratio.

Why are mutations that alter the amino acid sequence usually harmful?
OlgaM077 [116]

Answer:

This probably because they destroy a given character or give rise to a new one.

Explanation:

 Alteration here are the permanent changes found in the DNA structure. And are totally inheritable. An example is the case of sickle cell anaemia and haemophilia. People with this anaemia trait hardly live and reproduce even though they do not show ill effects.

 Therefore, this mutation alteration is harmful because they destroy a given character.

Deoxyribose Glucose Guanine Phosphate Ribose
Sergeu [11.5K]
There is no attached table, so it could not be told precisely which of the four molecules is the DNA. But, it is known that DNA consists of deoxyribose, guanine, and phosphate. 
The base unit of DNA is called a nucleotide. The nucleotide consists of a nucleobase (adenine - A, thymine - T, cytosine - C, and <u>guanine -G</u>), a monosaccharide <u>deoxyribose</u>, and a <u>phosphate </u>group. <span>By knowing this, it is easy to choose which molecule of those is the DNA.</span>
