Unit 2-Metabolic Rate Flashcards
Overall equation for aerobic respiration
Glucose + Oxygen → Carbon dioxide + Water
(energy is released)
C6H12O6 + 6O2 → 6CO2 + 6H2O
The rate of energy consumption in an organism
Metabolic Rate
What name is given to the metabolic rate at rest (periods of inactivity)?
Basal metabolic rate (BMR)
At rest, what does the body need to use energy for?
To keep vital organs such as the heart, lungs and brain functioning properly.
What can be measured to compare metabolic rates?
Oxygen consumption
Carbon dioxide produced
Heat produced
Equipment to measure the heat given off during metabolic processes
Calorimeter
Equipment to oxygen consumption and carbon dioxide production during metabolic processes
Respirometer
Found in vertebrates, require large quantities of oxygen and efficient gas exchange systems
High metabolic rate
What are the main blood vessels involved in the circulation of blood around the body?
Arteries
Capillaries
Veins
The role of arteries in the circulation of blood around the body
Carry blood away from the heart (under high pressure)
The role of capillaries in the circulation of blood around the body
Exchange nutrients, gases, and waste products between the blood and the body tissue.
The role of veins in the circulation of blood around the body
Carry blood back to the heart (under low pressure).
Atria
The top chambers of the heart which receive blood entering a vertebrate heart
Ventricles
Lower chamber of a vertebrate heart that distributes blood
Double Circulatory System
As the blood flows around the body it passes through the heart twice
