How many protons are pumped through each of the electron transport chain complexes?
complex i =
complex ii =
complex iii =
complex iv =

Complex I =   4 proton

Complex II =  0 proton

Complex III = 4 proton

Complex IV =2 proton

Explanation:

In the process of conversion of to to total three complexes are involved that are the integral proteins of the inner mitochondrial membrane and are involved in interacting with the electron thereby releasing proton.

Complex I =  Total four protons across the membranes

Complex II =  It do not have sufficient energy to pump out proton.

Complex III = Total four protons across the membranes

Complex IV = Total two protons across the membranes

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
