Respiration Flashcards
What is respiration?
The process by which living organisms exchange gases with their environment.
True or False: Respiration occurs only in animals.
False
Fill in the blank: The two main types of respiration are _____ and _____ respiration.
aerobic, anaerobic
What is the primary gas exchanged during respiration?
Oxygen
What is the byproduct of aerobic respiration?
Carbon dioxide and water
Which organelle is responsible for cellular respiration?
Mitochondria
Multiple choice: Which process produces the most ATP?
Aerobic respiration
What is anaerobic respiration?
A type of respiration that occurs without oxygen.
True or False: Lactic acid is a byproduct of anaerobic respiration in animals.
True
What is the equation for aerobic respiration?
Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP)
Multiple choice: Which of the following is NOT a product of anaerobic respiration?
Oxygen
What type of organisms primarily undergo fermentation?
Yeasts and some bacteria
Fill in the blank: The process of breathing in is called _____ and the process of breathing out is called _____.
inhalation, exhalation
True or False: Respiration and breathing are the same processes.
False
What is external respiration?
The exchange of gases between the atmosphere and the blood.
What is internal respiration?
The exchange of gases between the blood and the body’s cells.
True or False: ATP is the energy currency of the cell.
True
What is the primary energy carrier in cells?
ATP (Adenosine Triphosphate)
Multiple choice: Which of the following is a waste product of anaerobic respiration in yeast?
Ethanol
What is the importance of respiration for living organisms?
It provides energy necessary for cellular processes.
True or False: Carbon dioxide is a reactant in photosynthesis but a product in respiration.
True
What is the main purpose of glycolysis?
To break down glucose into pyruvate, producing a small amount of ATP.
