Lesson 2: Cellular Respiration Flashcards
(27 cards)
the process by which living cells break down glucose molecule and release energy
Cellular Respiration
Cellular Respiration Equation
C6H12O6 + 6O2 heat → CO2 + H2O + ATP
What are the three main stages of cellular respiration?
Glycolysis
Krebs cycle
Electron transport chain (Oxidative Phosphorylation)
product of glycolysis
2 ATP
2 Pyruvic Acid
2 NADH
produced in Kerbs Cycle
2 ATP
3 NADH
2 FADH2
6 CO2
What is the final electron acceptor in the electron transport chain?
Oxygen
Which organelle is the site of cellular respiration?
Mitochondria
True or False: Fermentation is an anaerobic process.
True
What is the net gain of ATP from one molecule of glucose during glycolysis?
2 ATP
What is the intermediate stage called before proceeding to Kerbs Cycle?
Pyruvate Oxidation
Where did Glycolysis happen
Cytoplasm
Where in mitochondria Kerbs Cycle happen
matrix
What is the main difference between anaerobic and aerobic respiration?
Anaerobic respiration occurs without oxygen, while aerobic respiration requires oxygen.
How many ATP molecules can be produced from one glucose molecule during aerobic respiration?
Up to 38 ATP
where did electron transport chain happen or oxidative phosphorylation?
inner membrane - mitochondria
Product of ETC (Electron Transport Chain)
34 ATP
this can causes fatigue
lactic acid
Meaning of PGAL
Phosphoglyceraldehyde
In which part of the cell does glycolysis occur?
Cytoplasm
What are the two types of fermentation?
Lactic acid fermentation and alcoholic fermentation.
What is the primary energy currency of the cell?
ATP
Fill in the blank: The process by which glucose is broken down to produce energy is called _____ respiration.
Cellular
Which process generates the most ATP during cellular respiration?
Electron transport chain
Name one condition under which fermentation occurs.
Lack of oxygen
