Measuring respiration Flashcards
factor affecting the rate of respiration
- concentration of oxygen
- concentration of glucose
- temperature
ways to measure respiration
- measuring the consumption of oxygen
- measuring the production of carbon dioxide
- measuring the change in temperature
how can you measure oxygen consumption
oxygen consumption can be measured using a respirometer. This apparatus has a tube filled with oxygen that has to lead to a selected container. Inside the container are an organism repairing and a substance that absorbs carbon dioxide. The change in the volume of water can be used to calculate the amount of oxygen consumed.
how can you measure the production of carbon dioxide
If the substance is weighed before and after, the difference in weight can be attributed to carbon dioxide production. An increase in volume will indicate the production of carbon dioxide
how can you measure temperature
The process of respiration is catabolic, meaning energy is being released as compounds are broken. When energy is released, temperature increases.
