New cards
What is the equation for cellular respiration?
**C6H12O6 + 6O2 → 6CO2 + 6H2O**
2
New cards
What does **C6H12O6 + 6O2 → 6CO2 + 6H2O** translate to? (What does it represent?)
Glucose + Oxygen → Carbon Dioxide + Water + ATP
3
New cards
What is the first step of cellular respiration?
glycolysis
4
New cards
Where does glycolysis take place in the cell?
cytoplasm
5
New cards
What happens in glycolysis?

hint: glucose is broken down into two _____ molecules and two _____ molecules
glucose is broken down into two molecules of pyruvic acid and two NADH molecules
6
New cards
What is the second step of cellular respiration?
Krebs cycle
7
New cards
Where does the Krebs cycle take place?
mitochondria
8
New cards
In the Krebs cycle, all living things

produce energy in (aerobic/anaerobic) respiration?
aerobic
9
New cards
The Krebs cycle uses ____ and turns it into ____ and _____.
oxygen, water, carbon dioxide
10
New cards
How many ATP does glycolysis produce?
2
11
New cards
How many ATP does the Krebs cycle produce?
2
12
New cards
What is the third step of cellular respiration?
ETC (Electron Transport Chain)
13
New cards
Where does ETC take place?
in the membrane of the mitochondria
14
New cards
How many ATP are produced through ETC?
32
15
New cards
In ETC, electrons travel across the _______, which allows ADP to gain a phosphorus and become ATP.
electrochemical gradient
16
New cards
How many total ATP are produced from cellular respiration?
36
17
New cards
What is the purpose of cellular respiration?
to make ATP
18
New cards
What organic molecule is broken down in cellular respiration?
glucose
19
New cards
What is making ATP without oxygen called?
fermentation
20
New cards
which is more efficient, cellular respiration or fermentation?
cellular respiration
21
New cards
Does fermentation use the citric acid (Krebs) cycle?
no, because the citric acid cycle needs oxygen
22
New cards
What are the two types of fermentation?
Alcohol fermentation and Lactic Acid fermentation
23
New cards
What is the final product of alcohol fermentation?
2 ethanol
24
New cards
Which type of fermentation decarboxylates?
alcohol fermentation
25
New cards
What is the final product of lactic acid fermentation?
2 lactate
26
New cards
ToF: carbon dioxide is released in the lactic acid fermentation process.
