REVISION – CHAPTER 4 – ENERGY FROM RESPIRATION
KEY WORDS:Aerobic respirationMitochondriaGlycogenAnaerobic respirationOxygen debt
ASSESSMENT:
What is the formula for aerobic respiration?
What is the role of mitochondria in respiration?
Why do organisms respire?
A student pedalled an exercise cycle at constant speed for 5 minutes. The student’s heart rate was recorded at one-minute intervals during the exercise and also during recovery
.
Describe the effect exercise has on the heart:
A student‘s breathing was monitored before and after vigorous exercise. The student breathed in and out through a special apparatus. The graphs show the changes in the volume of air inside the apparatus. Each time the student breathed in, the line on the graph dropped. Each time the
student
breathed out, the line went up
.
Describe the effect of exercise has on breathing:
What is anaerobic respiration?
How does it cause muscle fatigue?
What is oxygen debt?Slide5
