All living organisms must... (energy)
Produce energy from the environment in which they live, store energy for future use, and use energy in a controlled manner.
How is the energy produced in the electron transport chain used?
To form ATP or to pump hydrogen ions into the center of the thylakoid disc.
What happens once the electrons reach the end of the second electron transport chain?
The NADP+ takes them to the stroma of the chloroplast and combines with H+ to form NADPH
What happens in photolysis?
Water molecules are split for electrons; 2 water molecules yield an oxygen molecule, four electrons, and four hydrogen ions.
What happens after glycolysis? (With the pyruvic acid before the half step)
The pyruvic acid molecules move to the mitochondria
Tell about the half step with pyruvic acid. (Process and produces)
The pyruvic acid loses one molecule of CO2 and combines with Coenzyme A to form Acetyl CoA. This produces NADH and H+
How is the energy lost in CR electron transport chain used?
Pump H+ ions into the center of the mitochondrion or to form ATP
What is the final electron acceptor? What does it do?
It is oxygen; Oxygen combines with four H+ ions to form two molecules of water.
Tell about lactic acid fermentation.
Two molecules of pyruvic acid use NADH to form two molecules of lactic acid. The NAD+ is then free to be used in glycolysis in which two more ATP are formed. The lactic acid then is transported to the liver where it is converted back into pyruvic acid.
