Altering the three-dimensional structure of an enzyme might
alexandr402 [8]

The question is incomplete as it does not have the option which are:

  • change the amount of energy needed for a reaction.
  • prevent the substrate from binding the enzyme's active site.
  • change the type of substrate that binds the enzyme's active site.
  • change the type of product produced in the reaction.
  • prevent the enzyme from adding energy to a reaction

Answer

prevent the substrate from binding the enzyme's active site.

Explanation:

An Enzyme is a molecule composed of the amino acids in a 3 D conformation which catalyze or speed up a reaction.

The enzyme protein catalyses a chemical reaction by binding the substrate to its active pore formed by the 3D conformation of the protein and forming a complex of the substrate and enzyme.

If the 3D conformation of the enzyme is changed or altered then the active pore will be disrupted as a result of which the substrate-binding affinity and specificity will be changed which will not the reaction to proceed in forwarding direction or other terms the functionality of the protein will be lost.

Thus, the selected option is correct.

How do the industrial, agricultural, and residtual activites of human most likely affect the ground water in the area
Mekhanik [1.2K]

The industrial, agricultural, and residual activities of human  prevent most of the water from evaporating into the atmosphere. Pollutants from the activities enter through the soil and enter the water table.

<h3>What is atmosphere?</h3>

An atmosphere refer to as the layers of gases surrounding a planet or other celestial body. Earth's atmosphere is comprises of about 78% nitrogen, 21% oxygen, and 1% other gases.

Human activities such as pumping water from the ground for oil and gas extraction, may cause an aquifer to hold too much ground water. Too much ground water emission to streams can lead to erosion and change the balance of aquatic plant and animal species.

For more information regarding human activities cause pollution, refer:

meriva

Answer:

First, let's add the options to complete the question then we will solve

29

14

585

130

234,000

THE ANSWER IS 585

Explanation:

Formulae

N = (M1 x C) / M2

Where

N = population size

M1 = number marked in the first catch

C = the total number caught in the second catch

We are given

M1 = 130, C = 90, M2 = 20, N = ?

put the values into the formulae we have

(130 x 90) / 20 = 585

N = 585

Which color of light does chlorophyll b absorb more of than any other color?
Digiron [165]

Answer:

Chlorophyll b is a green colored, accessory photosynthetic pigment that helps in the process of photosynthesis by collecting enegry. It traps solar energy and transfers it to the chlorophyll a.

Chlorophyll b absorbs red and blue light of electromagnetic spectrum, which ranges from 650-680 and 450-480 nano meter. The light primarily absorbed by the chlorophyll b is blue light.

Thus, the correct answer is 'blue light.'

Carbon enters as carbon dioxide from the atmosphere when plants do what
fredd [130]

Answer:

Carbon storage and exchange

Explanation:

For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.
