Key is to lock as D. Substrate is to active site.

The correct answer is option option D

The enzyme-substrate model resembles the lock and key model. The key is specific to the lock and it cannot fit into some other lock.

As like that of lock and key, the substrate is specific to the active sites. The substrate binds to the active as the key fits in the lock.

In this way the product formation takes place.

The cooperative activity of drugs such as beta-lactam antibiotics and clavulanic acid, a beta-lactamase inhibitor, is known as

QveST [7]

Answer:

a. synergism

Explanation:

When two different drugs inhibit a single biochemical pathway of microbes less quantity of each drug is required in combination to produce the effect than when used separately. This effect is called synergistic interaction of drugs.

Both beta-lactam antibiotics such as penicillin and cephalosporin and clavulanic acid serve as beta-lactamase inhibitors and inhibit the beta-lactamase-producing bacteria. Therefore, beta-lactam antibiotics and clavulanic acid are used in combination to control these enteric bacteria.

Use the numbers 1, 2, 3, 4, and 5 to place the protein creation steps below in the correct order. Ribosome attaches to the mRNA.

kirza4 [7]

Answer: The correct sequence for the protein creation is as follows-

1) Information is transcribed in DNA to mRNA.

2) mRNA leaves the nucleus.

3) Ribosome attaches to the mRNA.

4) tRNA anticodon carries an amino acid that compliments the mRNA codon.

5) The chain of amino acids forms a protein.

According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.

The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.

This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.

Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).

Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.

There are two different species of finch that live on the same small island, species A andspecies

frosja888 [35]

On the islands of the Galapagos lives a group of birds called finches. There are 13 species in this group. These species have diverse ecologies--some eat seeds, some eat insects, some eat fruit, and some even eat cactus. Although the bodies of these species look fairly similar, their beaks are very different. That is because it is their beak that is adapted to these diverse ways of feeding (Figure 8.14).
