Cellular Respiration

Cellular Respiration SCC BIO 100 CH-7

QuestionAnswer
Process by which an electron is lost. Oxidation
Process by which an electron is gained. Reduction
A3-carbon molecule is converted to a 2-carbon molecule and a molecule of carbon dioxide is released. Acetyl CoA Formation
Stage where oxygen is required. Electron Transport Chain
Takes place in the inner mitochondrial compartment (matrix). Krebs Cycle
Shared by all living organisms. Glycolysis
Why are Hydrogen ions pumped across the inner mitochondrial membrane? Their movement generates ATP.
Why is the Krebs cycle a cycle? Because the first molecule in the pathway is also the last.
Which stages yields the greatest amount of ATP? Electron Transport Chain
Which stage is evolutionarily the oldest? Glycolysis
Which stage takes place in the cytoplasm? Glycolysis
Which stage releases the first molecule of carbon dioxide? Acetyl CoA formation
Describes an oxidation reaction. A substance donates and electron to another atom.
Cellular Respiration order Glycolysis - Krebs Cycle - Electron Transport Chain
Is found in the inner mitochondrial membrane or cristae. Electron transport chain & proton pump.
Can be oxidized to produce ATP..? Glucose, fats & proteins
Aka chemiosmosis Proton Pump
Together, these are known as oxidative phosphorylation. Electron transport chain & proton pump.
Is anaerebic Glycolysis
Has citric acid as one of its components. Krebs cycle
Consists of membrane proteins. electron transport chain
NADH, CoA and FADH2 3 major coenzymes of cellular respiration.
What is the carrier molecule of electrons in the move from glucose to the coenzyme? NADH
All the co-enzymes are derivatives from this. B vitamins
Used in the Kreb cycle. CoA
Product of fermentation in plants. Alcohol
Product of fermentation in animals. lactic acid
An enzyme that functions in cellular respiration by bringing together ADP and inorganic phosphate molecules to produce ATP. ATP synthase
The aerobic harvesting of energy. cellular respiration
Molecules that serve to transfer electrons from one molecule to another in ATP formation. electron carrier
A reduction-oxidation reaction where one side goes up in electrons and the other side must go down. Redox reaction

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.
