<h3>Oxidative Phosphorylation</h3>

Explanation:

The process by which ATP is generated by utilizing the large amount of energy released during the transfer of electrons from NADH or FADH₂ to the O₂ through a series of electron carrier present in the mitochondrial membrane is called oxidative phosphorylation.

The process of electron transfer is accompanied by the pumping of protons across inner membrane of mitochondria, from the mitochondrial matrix to intermembrane space establishing electrochemical proton gradient.

The ATP synthase complex present in the mitochondrial membrane allows the protons to move down the proton gradient as a result enough energy is released to add a phosphate group to ADP and form ATP inside the mitochondrial matrix.

) When predicting the phenotype of the offspring from a dihybrid cross, why is it so important that each gene is located in a di

Bond [772]

Answer:

a) The genes present on separate chromosomes exhibit indepedent assortment.

b) The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Explanation:

a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.

b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.

The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

What function do chloroplasts perform

Scilla [17]

Answer:

Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
