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 various processes involved in cellular respiration and oxidative phosphorylation? (assume that gramicidin does not affect the production of nadh and fadh2 during the early stages of cellular respiration.) sort the labels into the correct bin according to the effect that gramicidin would have on each process.

Respuesta :

A membrane produces an H+ channel when the protein gramicidin is incorporated into it, making the membrane highly permeable to protons (H+ ions).

Gramicidin is an antibiotic, right?

Gramicidin is a polypeptide antibiotic that, like nystatin, creates tiny pores in cell membranes but only permits the transport of monovalent cations while blocking anions. The cation selectivity sequence of gramicidin in lipid bilayers and cell membranes is identical.

When does phosphorylation take place and what is it?

Normally, DNA damage results in phosphorylation, which creates space surrounding broken DNA so that repair mechanisms can function.
