Cellular Respiration Flashcards
What Does ATP Stand for?
Adenosine TriPhosphate
What Is ATP?
molecule of energy
What Does a ATP Molecule consist?
- Adenine
- Ribose
- 3 phosphate groups
Who Have Cellular Respiration?
most living things
What is Cellular Respiration?
the process of energy conversion that releases energy (ATP) from food in the presence of oxygen
Formula of Cellular Respiration
C6 H12 06 + 602 —–> 6H20 + 6CO2 + Energy (36 ATP)
(glucose + 6 oxygen —-. 6 water + 6 carbon dioxide + energy)
Where is Cellular Respiration Found?
mitochondria & cytoplasm of cells
When Is Cellular Respiration?
ALL THE TIME!!!!
Why Cellular Respiration?
to release energy from food molecules to use energy consuming activities in the cell.
Types of Cellular Respiration
- Aerobic Respiration
- Anaerobic Respiration
Aerobic Respiration Stages
Stages:
1. Glycolysis
2. Kerb’s Cycle
3. Electron Transport Chain (ETC)
Glycolysis (Aerobic Respiration)
- occurs in the cytoplasm
- Does not require O2
Kerb’s Cycle
- citric acid cycle
- occurs in the mitochondria
- requires O2
Electron Transport Chain (ETC)
- occurs in the mitochondria
- requires O2
How much energy does Aerobic Respiration produce?
36 ATP
Anaerobic Respiration Stages
- Glycolysis
- Fermentation
Glycolysis (Anaerobic Respiration)
- occurs in cytoplasm
Where does Fermentation occur?
Cytoplasma
Types of Fermentation?
- Lactic Acid Fermentation
- Alcohol Fermentation
Who experiments Lactic Acid Fermentation
Happens in animals, fungi, and some bacteria
When is Lactic Acid Fermentation needed
- When Muscles cells can’t get enough oxygen to keep up with exercise needs, Lactic Acid is produced instead of ATP
- this causes muscle aches
- the process regenerates NAD+ so glycolysis can continue
What experiences Alcohol Fermentation
Yeast and Bacteria
What is Alcohol Fermentation
- a process where ethyl alcohol and CO2 are being produced instead of ATP
- this process regenerates NAD+ so glycolysis can continue
- this process produces beer + wine and causes bread to rise
Sequence of Respiration
- Breathing (O2)
- Circulation (O2)
- Cellular Respiration
- Circulation (CO2)
- Breathing (CO2)
Breathing (O2)
oxygen Is taken in and diffuses into the bloodstream
Circulation (O2)
Oxygen attaches to the hemoglobin to the RCB and is carried to cells
Cellular Respiration
oxygen and glucose enters the cells, combine in a chemical reaction to release energy (ATP)
Circulation (CO2)
Carbon dioxide diffuses into the bloodstream and is carries in the veins to the lungs
Breathing (CO2)
carbon dioxide is removed
