1. Respiration Flashcards
(15 cards)
What is the chemical reaction that takes place in all living organisms to release energy?
Respiration
Respiration is essential for energy production in cells.
Where does respiration take place in cells?
Mitochondria
Mitochondria are known as the powerhouse of the cell.
What type of respiration uses oxygen?
Aerobic respiration
Aerobic respiration is more efficient than anaerobic respiration.
What type of respiration does not use oxygen?
Anaerobic respiration
Anaerobic respiration occurs in low oxygen conditions.
What is the main product of aerobic respiration?
Energy
Aerobic respiration also produces carbon dioxide and water.
What is the chemical equation for aerobic respiration?
6O2 + C6H12O6 → 6CO2 + 6H2O + Energy
This represents the complete breakdown of glucose.
What is produced during anaerobic respiration in fungi?
Ethanol (alcohol)
This process is known as fermentation.
What are the commercial uses of anaerobic respiration in fungi?
- Brewing wine and beer
- Baking
In baking, CO2 produced helps dough rise.
What is the byproduct of anaerobic respiration in muscles?
Lactic acid
Lactic acid can cause muscle fatigue and cramps.
What happens when muscles are overworked during anaerobic respiration?
They produce lactic acid due to high energy demand
Blood cannot supply enough oxygen during intense activity.
What is oxygen debt?
The need for oxygen to fully oxidize lactic acid
Oxygen debt occurs after anaerobic activity when lactic acid must be broken down.
Fill in the blank: Anaerobic respiration produces a ______ amount of energy.
small
This contrasts with the large amount of energy produced by aerobic respiration.
True or False: Anaerobic respiration can occur in situations where oxygen levels are high.
False
Anaerobic respiration occurs when oxygen is low or absent.
What are the end products of anaerobic respiration in animals?
Lactic acid and energy
Lactic acid buildup can lead to fatigue.
What is the energy source used in both aerobic and anaerobic respiration?
Glucose
Glucose is broken down to release energy in both processes.
