Q2 Aerobic & Anaerobic Respiration Flashcards
The sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.
METABOLISM
2 TYPES OF METABOLISM
Catabolism, Anabolism
Type of metabolism that Breaks down bigger molecules to smaller molecules
Catabolism
Type of metabolism that makes and releases energy
Catabolism
Type of metabolism wherein potential energy is converted into kinetic.
Catabolism
Type of metabolism that is Required in order to perform different activities in living entities.
Catabolism
Type of metabolism that
Constructs smaller molecules into bigger molecules
Anabolism
Type of metabolism that Uses energy
Anabolism
Type of metabolism wherein Kinetic energy is converted into potential energy
Anabolism
Type of metabolism that is required for maintenance, growth, and storage.
Anabolism
- When a molecule loses an electron
- NADH to NAD+
OXIDATION
- When a molecule gain an electron
- NAD+ and NADH
REDUCTION
The physical and chemical processes (such as breathing and diffusion) by which an organism supplies its cells and tissues with the oxygen needed for metabolism and relieves them of the carbon dioxide formed in energy-producing reactions.
RESPIRATION
3 STEPS OF RESPIRATION
- External respiration
- Internal respiration
- Cellular respiration
Step of respiration wherein it is between the environment and lungs
External respiration
Step of respiration wherein it is between the blood and cell
Internal respiration
Step of respiration that involves the conversion of food to energy.
Cellular respiration
Chemical reaction which breakdown nutrients to release energy
Organisms breakdown glucose from food to create energy, known as adenosine triphosphate (ATP)
CELLULAR RESPIRATION
It occurs inside the living cells of all types of organisms (from prokaryotic bacteria and Achaeans to eukaryotic protests, fungi, plants, and animals) to carry out various vital activities like muscle contraction, nerve transmission, cell division, etc.
CELLULAR RESPIRATION
SIGNIFICANCE OF CELLULAR RESPIRATION?
Muscle contractions require energy to work.
Muscle cells can only store 6 to 10 seconds muscular contraction worth of ATP
To provide the muscle more energy the process of cellular respiration must simultaneously happen.
2 TYPES OF CELLULAR RESPIRATION
- Aerobic Respiration
- Anaerobic Respiration
Aerobic Respiration (verbal formula)
Glucose + oxygen ➜ CO2 + Water + Energy
Anaerobic Respiration (verbal formula) Animal
Glucose → Lactic Acid + Energy
Anaerobic Respiration (verbal formula) Bacteria, Plants, and Yeasts
Glucose → ethanol + carbon dioxide + Energy
Aerobic Respiration (chemical formula)
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
Anaerobic Respiration (chemical formula) Animal
C6H12O6 → 2C3H6O3 + ATP
Anaerobic Respiration (chemical formula) Bacteria, Plants, and Yeasts
C6H12O6 → 2C2H5OH + 2CO2 + ATP
2 types of Anaerobic Respiration
- Lactic Acid Fermentation
- Ethanol Fermentation
Which type of Anaerobic Respiration is this?
Breakdowns glucose to produce ATP without the use of oxygen.
Lactic Acid Fermentation
What are the 2 STEPS OF LACTIC ACID FERMENTATION
Glucose → Lactic Acid + Energy
- Glycolysis
- Fermentation
Glycolysis
Glucose is __________ by _______, ___________, and ________
Location: __________
Glucose is broken down by ATP, NAD+, and Enzymes (E)
Location: Cytoplasm in the cytosol
Stages of glycolysis
- 2 ATP and enzymes_____________
- Enzymes add free_____________
- Re_____________
- Formation of _____________
- 2 ATP and enzymes breakdown glucose to form glyceraldehyde -3- phosphate (PGAL)
- Enzymes add free P to form 1,3 biphosphoglycerate
- Reduction/ Formation of 2 NADH
- Formation of 4 ATP
END OF GLYCOLYSIS WE HAVE:
- 2 pyruvate (C3H4O3)
- 2 NADH
- 4 ATP (Net gain of 2 ATP)
STEP 2 OF ANAEROBIC RESPIRATION: ______________
Occurs when cells do not have enough ______________. Makes sure that______________
LOCATION: ______________
STEP 2: FERMENTATION
Occurs when cells do not have enough oxygen. Makes sure that glycolysis will continue.
LOCATION: Cytoplasm in the cytosol
STAGES OF LACTIC ACID FERMENTATION
- Formation of Lactic Acid
- Regeneration of NAD+
END OF LACTIC ACID FERMENTATION WE HAVE:
- 2 lactic acid C3H6O3
- 4 ATP (net gain of 2)
- 2 NAD+
USES OF LACTIC ACID FERMENTATION
- Provide immediate e_________
- Used in making s_________
- Used in p_________
- Used in making y_________
- Provide immediate energy during strenuous exercises
- Used in making sourdough bread
- Use in preserving cucumbers to make pickles
- Used in making yogurt
ETHANOL FERMENTATION
Chemical Formula
C6H12O6 → 2 C2H5OH + 2 CO2 + ATP
ETHANOL FERMENTATION
Verbal Formula
Glucose → Ethanol + Carbon Dioxide + ATP
ETHANOL FERMENTATION
- Occurs in y__________
- Location: C_______
- Occurs in yeasts and some plants
- Location: Cytosol
STEPS OF ETHANOL FERMENTATION
- Glycolysis
- Fermentation
STAGES OF ETHANOL FERMENTATION
- Breaking down of pyruvate by an enzyme to produce CO2
- Regeneration of 2 NAD+
END OF ETHANOL FERMENTATION WE HAVE
- 2 CO2
- 2 C2H5OH
- 4 ATP (net gain of 2 ATP)
- 2 NAD+
Why is ethanol fermentation important?
Because it regenerates NAD+ which is needed to start glycolysis again
USES OF ETHANOL FERMENTATION
- Used in making _________ (CO2 _________ , e _________ _________ during baking)
- Used in making _________ and _________
- Used in making most bread (CO2 forms bubbles that make bread fluffy, ethanol evaporates during baking)
- Used in making wine and beer
SUMMARY OF ANAEROBIC RESPIRATION
Process do/don’t require_____________

2 types: _____________
Lactic acid fermentation happens when animals _____________
Ethanol fermentation happens in some _____________
Process do not require energy.
Breaks down glucose to produce 2 ATP.
Happens in the cytosol of the cytoplasm.
2 types lactic acid fermentation and ethanol fermentation
Lactic acid fermentation happens when animals lack oxygen during strenuous activity
