Respiration Flashcards
(14 cards)
What is the word equation for anaerobic respiration in human cells?
Glucose → lactic acid + a little energy
Lactic acid is produced when glucose is broken down without oxygen.
What is a consequence of lactic acid buildup in muscle cells?
Muscle fatigue and cramp
Lactic acid is poisonous and can lead to the cessation of muscle cell function.
What happens to lactic acid during recovery?
It is transported to the liver, where it is broken down into carbon dioxide and water
This process requires extra oxygen, referred to as oxygen debt.
What is the term used for the extra oxygen required to break down lactic acid?
Oxygen debt
Oxygen debt is the amount of oxygen required to metabolize lactic acid after anaerobic respiration.
What are two main disadvantages of anaerobic respiration in humans?
- Muscle fatigue and cramp from lactic acid
- Oxygen debt from breaking down lactic acid
These disadvantages can impact physical performance and recovery.
Can plant cells carry out anaerobic respiration?
Yes, in conditions lacking oxygen
Plant cells can perform anaerobic respiration, similar to animal cells.
Where does anaerobic respiration take place in plant cells and yeast?
In the cytoplasm
Anaerobic respiration occurs in the cytoplasm, unlike aerobic respiration which occurs in mitochondria.
What is the raw material needed for anaerobic respiration in plants and yeast?
Glucose
Glucose is the primary substrate for both anaerobic and aerobic respiration.
What are the products of anaerobic respiration in plants and yeast?
- Ethanol
- Carbon dioxide
The word equation for this process is: glucose → ethanol + carbon dioxide.
Fill in the blank: The word equation for anaerobic respiration in plants is: Glucose → _______ + Carbon dioxide.
Ethanol
This process occurs when oxygen is not available.
Respiration releases energy. What processes is this used for?
Movement, warmth, chemical reaction, active transport
What is the word and chemical equation for aerobic respiration in animals?
Glucose + oxygen —> carbon dioxide + water + ATP
C6 H12 O6 + 6O2 —> 6CO2 + 6H2O + ATP
What is the main site of aerobic respiration?
Mitochondria
Anaerobic respiration (in animals) occurs where?
Cytoplasm of cells
