Chapter 2, 3 + 4 - ATP, Photosynthesis And Respiration Flashcards
What does ATP stand for?
Adenosine triphosphate.
What is metabolism?
All the chemical reactions which take place in living organisms.
What is photophosphorylation?
The part of the light dependent reaction of photosynthesis in which energy released in the electron transfer system is used in the production of ATP.
What is oxidative phosphorylation?
The part of the respiratory pathway in which energy released in the electron transfer system is used in the production of ATP.
What is substrate level phosphorylation?
When phosphate groups are transferred from donor molecules to ADP to make ATP. Occurs in glycolysis and Krebs cycle.
What is photosynthesis?
The process by which plants are able to use light energy to convert carbon dioxide into carbohydrates.
What is photolysis?
The splitting of water molecules, with light, to form electrons, hydrogen ions and an oxygen molecule.
What is the law of limiting factors?
At any given moment, the rate of a physiological process is limited by the factor that is at its least favourable.
What is the light dependent reaction?
The process in which light energy is absorbed by chlorophyll and used to produce ATP and reduced NADP during photosynthesis - occurs in the thylakoids.
What is the light independent reaction?
The process by which carbon dioxide is reduced to form a carbohydrate during photosynthesis - occurs in the stroma.
What is glycolysis?
The part of the biochemical pathway in which a molecule of glucose is broken into two three-carbon pyruvate groups.
What is a coenzyme?
A molecule, other than the substrate, that is needed for an enzyme to work. Usually transports atoms or molecules from one enzyme controlled reaction to another.
What is the electron transport chain?
A chain of carrier molecules in which energy released in the passage of electrons from one molecule to another is used to produce ATP.
