Flashcards in B3c-respiration Deck (16)
What is the word equation for aerobic respiration?
Glucose + oxygen --> carbon dioxide + water
What are some life processes that require energy from respiration?
Control of body temperature in mammals
What is the symbol equation for aerobic respiration?
C6H12O6 + 6O2 --> 6CO2 + 6H2O
What is respiratory quotient?
It tells you whether someone is respiring aerobically or anaerobically
What is the equation for respiratory quotient?
RQ = carbon dioxide / oxygen used
What is ATP?
An energy source for many processes in cells and transports energy to where its needed
How can the rate of oxygen consumption be used as an estimate of metabolic rate?
When respiration rate increases both oxygen consumption and carbon dioxide production increases
Aerobic respiration requires oxygen
What is the metabolic rate?
The amount of energy being used
Why is the rate of respiration influenced by changes in temperature and pH?
Respiration is controlled by enzymes
Why do breathing and pulse rates increase during exercise?
When you do vigorous exercise your body needs to supply more oxygen to your muscles for aerobic respiration
Why does anaerobic respiration take place in addition to aerobic respiration?
When you do vigorous exercise your body cant supply enough oxygen to your muscles for aerobic respiration
What is the word equation for anaerobic respiration?
Glucose--> lactic acid
How is lactic acid removed during recovery?
-hard exercise causing lack of oxygen in cells
-the incomplete breakdown of glucose
-continued panting replacing oxygen allowing aerobic respiration
-increased heart rate ensuring that blood carries lactic acid away to the liver
What is respiration?
Respiration is a chemical reaction that takes place in the mitochondria. It is when glucose reacts with oxygen to produce carbon dioxide and energy is released
Describe an experiment to measure resting pulse rate and recovery time after exercise
-meaure heart rate
-jumping jacks for 1 minute
-measure heart rate again
