Q2: Cellular Respiration Flashcards
True or False
Ultimately, most of the energy that is utilized by the living organisms of every ecosystem comes from the sun.
True
True or False
Glycolysis can work with the presence of oxygen.
False
It is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
Cellular Respiration
Organisms that do not depend on oxygen degrade foodstuffs in a process called
Fermentation
It is a sequence of 10 chemical reactions taking place in most cells that breaks down a glucose molecule into two pyruvate (pyruvic acid) molecules.
Glycolysis
How many ATPs does glycolysis generate ?
4 ATPs
What are the three stages of cellular respiration?
Glycolysis, Kreb’s Cycle/ Citric Axif Cycle, and Electron Transport Chain/ Oxidative Phosphorylation
It is when the pyruvic acid molecules enter the mitochondria and through a series of chemical reactions.
