Answer: process by which cells obtain energy from glucose. During respiration, cells break down simple food molecules such as sugar and release the energy they contain. Heterotrophs consume autotrophs in order to obtain energy. autotrophs produce the reactants needed by heterotrophs for cellular respiration.
<em>Membrane proteins that aid in the passive transport of substances do so without the use of ATP. During active transport, ATP is required to move a substance across a membrane, often with the help of protein carriers, and usually against its concentration gradient.</em>
