Unit 3: Metabolic Processes Flashcards
What is Cellular Respiration?
It is a CATABOLIC reaction that breaks down glucose to produce water and carbon dioxide.
What is Photosynthesis?
It is a ANABOLIC reaction that creates glucose from water and carbon dioxide.
Where does Cellular Respiration take place? (Hint: CMII)
- Cytoplasm
- Mitochondrial Matrix
- Intermembrane Space.
- Inner Membrane.
Where does Photosynthesis take place? (Hint: CCTLS)
- Chloroplast
- Chlorophyll
- Thylakoid Membrane
- Lumen
- Stroma
What is Glycolysis?
Cellular Respiration - Cytoplasm:
Breaks down Glucose into its components (ATP and NADH) does not need oxygen.
What is Pyruvate Oxidation?
Cellular Respiration - Mitochondrial Matrix:
The products of glycolysis bond with enzymes and are transformed before they are sent to the Krebs cycle.
What is the Krebs Cycle?
Cellular Respiration - Mitochondrial Matrix
Oxidizes the compounds from glucose.
What is Electronic transport Chain?
Cellular Respiration - Mitochondria AND chloroplasts.
Separates the electrons from the protons. Electrons are sent to the inner membrane and form water. Protons are sent to the intermembrane to create the electrochemical gradient.
What is Chemiosmosis?
Connects ATP Synthesis to the electrochemical gradient.
What is ATP Synthase?
It bonds ADP and phosphate groups to create ATP
Where does the Calvin Cycle happen?
The Stroma of the Chloroplast
What is the least useful light for photosynthesis?
Green light
How are the Krebs Cycle and the Calvin cycle similar?
They both regenerate a starting compound (reactant)
What is Rubisco?
An enzyme that “fixes” carbon dioxide in the Calvin cycle.
What is a Redox Reaction?
The transfer of one or more electrons from one molecule to another.
Oxidation
When an molecule loses electrons
Reduction
When a molecule gains electrons
What are the 3 carrier molecules?
NADH, FADH2 and FADH
What are the steps of Cellular Respiration?
- Glycolysis
- Pyruvate Oxidation
- Krebs cycle
- Electron Transport Chain.
What are the steps of Photosynthesis?
- Light Dependent Reactions
- Photosystem II
- Electronic Transport Chain
- Photosystem I
- Calvin Cycle
First Law of Thermodynamics
Energy can be moved around but cannot be created nor destroyed
