3.6 Cellular Respira

AP Biology 3.6 Cellular Respiration Vocabulary

QuestionAnswer
Acetyl Coenzyme A This is produced from the decarboxylation of pyruvate; used to "feed" into the Krebs cycle
ADP this molecule gets phosphorylated and turns into the main unit of energy
Aerobic Respiration Takes place with the presence of oxygen (in mitochondria) and is the process by which organisms produce energy through the use of mitochondria
Anaerobic respiration Takes place when oxygen is not present (in cytoplasm)
ATP energy : Adenosine triphosphate produced as a result of ADP getting phosphorylated
ATP Synthase It is the enzyme of which protons diffuse through in order to produce ATP
Carbon Dioxide a waste product of cellular respiration that is produced as a result of decarboxylation reactions that happen during the link reaction and during the Krebs Cycle
Cellular respiration The controlled release of energy from organic compounds in cells to form ATP
Coenzyme A (acetyl CoA) it decarboxylates pyruvate in order to convert pyruvate into acetyl Coenzyme A
Cytoplasm location in cells where glycolysis takes place
Decarboxylation Loss of carbon dioxide from a molecule.
Electron transport chain This is the part of cellular respiration that refers to: The transfer of electrons from electron carriers to electron acceptors via redox reactions and couples this electron transfer with the transfer of protons across a membrane
Electrons negatively charged components of atoms
Ethanol a produce of anaerobic respiration with plants
FADH2 An electron carrier
Glucose Monosacharide found in plants which is used for the conversion of energy. Composed of 6 carbons
Glycolysis Metabolic pathway that converts glucose into pyruvate
Link reaction (Pyruvate Oxidation) Occurs in the matrix of the mitochondrion in which pyruvate is converted into Acetyl Co enzyme A
Lysis The conversion of hexose biphosphate into 2 triose phosphate molecules
Matrix The space in between the inner membrane and cristae found in the mitochondrion where cellular respiration and specifically the Krebs Cycle takes place
mitochondrion organelle with a double-membrane that is the main site for cellular respiration in the presence of oxygen
NAD+ A co-enzyme found in living cells; After REDUCTION
NADH An electron carrier
Oxidation is loss (of electrons)
Reduction is Gain (of electrons)
Phosphorylation When phosphate is added to ADP to form ATP
Pyruvate Product of glycolysis that is used and synthesised by metabolic pathways
Chemiosmosis Describes how the energy from electron transport in the ETC is used to create a proton gradient

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
