Answer:

transport of protons (H+) from low concentration in the mitochondrial matrix to high concentration in the mitochondrial intermembrane space

Explanation:

atpase pump can also be called atp synthase. this enzyme catalyses atp formation from adenosine diphosphate and phosphate. it has f1, stalk and f0 components. 3 positive hydrogen ions go through to make 1 adenosine triphosphate molecule. oxidative phosphorylation has to do with the loss of electrons. there would be electrons loss from NADH to FADH2. Cytochromes carries them through different series of transferases from I to IV and while on this positive hydrogen ions are released into mitochondrial matrix

positive hydrogen ions are moved back to lumen through adenosine triphosphate channels. a process called chemiosmosis. the pro

A sexually reproducing animal has two unlinked genes (on separate chromosomes), one for head shape (H) and one for tail length (
Verizon [17]

Answer:

a) HT

Explanation:

This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.

According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.

Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.

Therefore, HT is the genotype possible in a gamete of parent: HhTt.
