Answer: The total magnification of a low power objective lens combined with a 10x eyepiece lens is 100x magnification, giving you a closer view of the slide than a scanning objective lens without getting too close for general viewing purposes.

Enzymatic and other proteinic activity is limited by pH. 2) Slight deviations from normal pH can shut down metabolic pathways. 3) The structure and function of macromolecules are pH dependent.

<h3>How does the pH levels affect enzymes and proteins?</h3>

Enzymes, like all proteins, are polypeptidic molecules.

They need to get an accurate tridimensional structure to accomplish their function.

There is a limit of temperature and pH level at which they lose that structure and denaturalize.

<u>pH changes</u>

The most accurate configuration for the best catalytic performance depends on the charge of the lateral chains and the environmental pH.

Enzymes have ionizable chemical groups in the lateral chains of their amino acids.

Depending on the environmental pH, these groups will have a positive, negative, or neutral charge.

There is an optimum pH level at which enzymes get the best configuration to accomplish their functions.

Most enzymes are sensitive to any change in pH, which might drastically affect their activity. So every enzyme has its optimum pH level, and any slight deviations will cause the enzyme denaturalization, hence, its activity loss.

Whenever the enzyme loses its configuration, and hence, its function, the whole pathway in which it is involved is interrupted.

Options 2 and 3 are correct.

Slight deviations from normal pH can shut down metabolic pathways.
The structure and function of macromolecules are pH dependent.

Most enzymes require an acidic pH to function properly.
Slight deviations from normal pH can shut down metabolic pathways.
The structure and function of macromolecules are pH dependent.
Hormones require a blood pH of at least 77 to function,
A drop in blood pH causes dehydration

Compare ionic solids and liquids

Lapatulllka [165]

At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas, whereas ionic compounds exist only as solids, Ionic compounds exist in stable crystalline structures. Therefore, they have higher melting and boiling points compared to covalent compounds.

Which reason provides the best explanation of why a bar graph was selected to show the data in the table?

S_A_V [24]

Hey there,

Your question states: <span>Which reason provides the best explanation of why a bar graph was selected to show the data in the table?
1. Bar graphs are used to compare separate items.
2.Bar graphs are used when data are continuous.
3. Bar graphs are not good for categorical data.
4. Bar graphs are the easiest to construct and to read.

Your correct answer would be (</span><span>Bar graphs are used to compare separate items.)

When you see a (bar graph), you would see the different details in each bar. They show you different rating or uses of each subject.

(There would be a attachment below to show you)

Hope this helps.

Alcohol dehydrogenase (ADH) is an enzyme that aids in the decomposition of ethyl alcohol (CH3OH) into nontoxic substances. Methy

Thepotemich [5.8K]

Answer:

d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.

Explanation:

Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.

Their active sites are primary protein 3D structure for binding with substrates during reactions.

Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,

This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites occupied, therefore denying the inhibitor methylalchol chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites
