If flavoprotein performs the alternate pathway of transferring an electron directly to oxygen rather than to the next component

of the etc, what toxic molecules are produced? what other effects of bypassing the etc have on the cell?

Alona [7]3 years ago

If flavoprotein performs the alternate pathway of transferring an electron directly to oxygen rather than to the next component of the ETC, TWO toxic molecules are produced. These cellular toxic molecules are HYDROGEN PEROXIDE (H2O2) AND SUPEROXIDE RADICALS (O2-). These toxins are reactive oxygen species (ROS) that produce free radicals.

This alternate pathway also results in damaging of the cells and early aging of the cells. There are enzymes such as catalase and superoxide dismutase that catalyse the reaction for the degradation of these toxins.

A couple plans to have a child. the mother is homozygous for an autosomal recessive mutation. the father is heterozygous for the
adoni [48]

<u>Answer</u>:

  • The possible genotypes of the children are Hh and hh.
  • The probability of genotype Hh = 1/2
  • The probability of genotype hh = 1/2

<u>Explanation</u>:

  • <em>Autosomal genes</em> are the genes present on any of the chromosomes except the sex chromosomes.
  • An autosomal recessive mutation is the mutation in an autosomal gene which only expresses itself in the phenotype in homozygous condition and affects both males and female equally.
  • For the given question, let the autosomal gene be represented by H (dominant) and h (recessive)
  • According to the question,

Since the <em>mother</em> is homozygous her genotype would be hh and the <em>father</em> is heterozygous so his genotype would be Hh.

The following cross is made to know the genotypes of the children :

hh X Hh--------> Hh Hh hh hh

So the <em>possible genotypes of the children are Hh and hh as shown in the cross. </em>

Note : An image is attached representing the cross in a Punnett square.

  • The probability of an event = No. of favourable outcomes/total no. of outcomes

The probability of occurrence of genotype Hh would be = 2/4 = 1/2

Similarly, the probability of occurrence of genotype hh would be 2/4 = 1/2

Global air circulation cells move air _____.
tino4ka555 [31]

Global air circulation cells move air "clockwise in the Northern hemisphere and counterclockwise in the Southern hemisphere".

<u>Answer:</u> Option B

<u>Explanation:</u>

Global circulation is defined as the global connection of winds, through which the requisite heat transport  from tropical latitudes to polar latitudes carried out. Each hemisphere comprises with three cells, such as Hadley, Ferrel and Polar cell, air circulation take place in this through the complete depth of the troposphere.

The worldwide circulation cells allow passage of air in clockwise pattern in the northern hemisphere while in southern hemisphere circulate in counter-clockwise pattern from equator to poles but in different directions and at different latitudes.

What type of mutations do scientists look for in a molecular clock?
OleMash [197]

The molecular clock tracks down nucleotide sequences for DNA or amino acids that contain sequences of proteins. Scientists use this to deduce the time in history where life forms possibly have diverged. This technique is also known as a gene clock or an evolutionary clock.
