Production of electricity by nuclear power releases a greater amount of greenhouse gases than production of electricity
using coal.
true
false

False.

Explanation:

A small mass defect in a nuclear reactor is responsible for producing a large amount of energy. The end products might be radioactive and might have to be disposed correctly but I doubt that there would be any sort of greenhouse gas emission.

Coal on the other hand is a, vaguely speaking, a group of hydrocarbons, which on combustion gives carbon dioxide. Carbon dioxide is a major greenhouse gas responsible for greenhouse effect along with other gases like methane which could also be present in coal in some quantity.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
