An investigation is carried out to determine the effect of exercise on the rate at which a person can squeeze a clothespin.
The dependent variable for this experiment is the
time the student was squeezing the clothespin
number of times the student was able to squeeze the clothespin
strength of the student
length of the clothespin
During periods of vigorous physical activity, a person's breathing and heart rates increase. This enables the cells of the body to perform more efficiently because it helps the cells to
remove waste products faster
store excess glucose in muscles
reduce the amount of ATP produced
convert more oxygen to glucose
Muscle fatigue is caused by
the build up of waste products such as lactic acid
the build up of oxygen
What are the inputs of cellular respiration?
Glucose and oxygen
carbon dioxide, ATP, water
What are the outputs of cellular respiration?
Glucose, Oxygen
ATP, Carbon Dioxide and Water
