When the protein gramicidin is integrated into a membrane, an H channel forms and the membrane becomes very permeable to protons

(H ions). If gramicidin is added to an actively respiring muscle cell, how would it affect the rates of electron transport, proton pumping, and ATP synthesis in oxidative phosphorylation?
a.remains the same
b.proton pumping rate
c.electron transport rate
d.rate of oxygen uptake

Answer:

The rates of electron transport, proton pumping, remains the same.

There is a decrease in the rate of ATP synthesis in Oxidative Phosphorylation.

Explanation:

Gramicidin is a proteinous (peptide) that forms spores. Gramicidin causes a series of harmful actions when it comes in contact with a membrane.

When Gramicidin comes in contact with or it is integrated into the membrane of an actively respiring membrane, the permeability of the membrane increases such that it begins to lose protons causing the production of ATP( Adenosine Triphosphate) in the muscles during oxidative phosphorylation to cease.

Although, the rates of electron transport remains the same and the pumping of protons remains the same.

Answer:

c.electron transport rate

Explanation:

Gramicidin is a substance which blocks the production of ATP by inhibiting oxidative phosphorylation and glycolysis process occurs in the process of cellular respiration, responsible for the reduction of  energy and cell death also occurs. Oxidative phosphorylation is a process in which ATP molecules are formed by the transfer of electrons from NADH to oxygen. This process occurs in the mitochondria of the cell in the availability of oxygen where ATP production occurs. so electron rate is greatly affected and low amount of ATP are produced.

What is the initial form for a protein?
alexgriva [62]

Protein primary structure is the linear sequence of amino acids in a peptide or protein. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end. Protein biosynthesis is most commonly performed by ribosomes in cells.

Which statement describes Mendel’s hypotheses regarding gametes?
Mariana [72]

The principle of segregation given by Gregor Mendel based on his experiments with the pea plants states that alleles of a gene for any trait are segregated during the formation of the gametes. Therefore, a gamete contains only one allele of a gene. When the male and female gamete combines during fertilization, the two alleles (one from each gamete) combine to form the gene.

Hence, the correct answer is 'Option B - A gamete carries one allele for a gene'.

In complete dominance, when does the dominant trait show up?
Morgarella [4.7K]
In COMPLETE dominance, the dominant trait shows up when the dominant allele is present.

In INCOMPLETE dominance, the dominant trait does not show up. What shows up is a middle ground between the dominant and recessive traits.

In CODOMINACE, both the dominant and recessive traits are present.
