Respiration in Plants
11 lessons97 min5 simulations10 practice questions
This chapter follows a glucose molecule as a cell takes it apart, step by step, to fill ATP. It starts with why plants manage without lungs, then runs through glycolysis in the cytoplasm, fermentation when oxygen is short, and the link reaction, Krebs' cycle and electron transport inside the mitochondrion, before totting up the ATP, showing that the pathway builds as well as breaks, and measuring substrates with the respiratory quotient.
Also called: glycolysis · Krebs cycle · electron transport chain · cellular respiration
