Answer:
Feedback inhibition.
Explanation:
It is feedback inhibition pathway because it is a cellular control process in metabolic part wat in which the output of a metabolic pathway binds to an enzyme at the regulatory sites which is distinct from the active sites of the substrates, causing a conformational changes on the enzyme which then makes it to slow down or inhibit it's production or synthesis.
This help to prevents excess of the high levels of the product from accumulating in the cell
Answer:
The correct answer is - C. The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.
Explanation:
DNA is the genetic material of most of the living organisms. In this question, Joe wants to study to see the effect of folic acid on the synthesis of the DNA. Folic acid ae the essential nutrients or vitamin for the synthesis of nitrogen bases of the DNA that are purines and pyrimidines. A dependent variable and an independent variable are two important part of any experiment.
A dependent variable is a variable being tested and measured. In the experiment Jon is conducting, the amount of DNA becomes a dependent variable that is being tested and measured in the presence of folic acid. And folic acid is the independent variable tested to check the formation of DNA in bacteria.
Thus, the correct answer is - C. The amount of folic acid is the independent variable, and the DNA synthesized is the dependent variable.
The answer would be true
Deuterostomes are superphylum of Animalia kingdom in taxonomy. The word means the second mouth in the Greek language which characterizes this group with an anus, opening on the other sides of the mouth to dump waste. The member of this superphylum is Chordata, Hemichordata, and Echinodermata.
Answer:
Answer is C. By changing the shape of protein.
Explanation:
The site where the substrate binds and the chemical reaction take place is known as the active site.
Note that , if there is changes in the pH, it can affect the active site of the amino acid residue which usually have acidic or basic properties that is important for catalysis, thereby making it hard for substrate to bind.
Answer:
Option-A
Explanation:
β-Lactam antibiotics are the antibiotics that contain β-Lactam rings in their structures like in cephalosporins and penicillin.
The antibiotics act by inhibiting or disrupting the process of cell wall formation in the bacteria which is mediated by an enzyme called penicillin-binding proteins.
To bind covalently to the PBP proteins, the antibiotic has to diffuse through the bacterial cell wall. since the gram-negative bacteria contain an additional lipopolysaccharide layer which decreases the penetration of the antibiotic, therefore, the gram-positive bacteria lacking the additional layer are more susceptible than gram-negative bacteria.
Thus, option-A is the correct answer.
