How can a lock and key be used to describe an enzyme?​

Biology

QveST [7]3 years ago
6 0

Answer:

it is they lock and key theory

Explanation:

The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme).

Bacteria can reproduce quickly by means of binary fission. Because of this, after binary fission
Dahasolnce [82]

C) all the offspring will be genetically identical.

Explanation:

During binary fission, all the offspring will be genetically identical and little to no variation occurs.

Binary is an asexual form of reproduction which does not involve the combination of gametes from the parents.

  • During binary fission, the parent simply divides to produce young ones.
  • In this process, the offspring replicates the genetic component of the parents making it identical.
  • The offspring is a direct copy of the parents.
  • It is only in sexual reproduction that genetic materials are exchanged between the parents and offspring. This leads to genetic variation.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96
