WebIncluded among the rate-limiting steps of the dark stage of photosynthesis are the chemical reactions by which organic compounds are formed by using carbon dioxide as a carbon source. The rates of these reactions can be increased somewhat by increasing the carbon dioxide concentration. Since the middle of the 19th century, the level of carbon dioxide in …
WebIf the rate of photosynthesis increases (e.g. by increasing the brightness of the lamp) the number of oxygen bubbles or volume of oxygen produced will also increase. Measuring the volume of... WebOct 21, 2024 · Cut the pondweed into small pieces and place it in a container of water. Connect the oxygen sensor to the container and turn it on. The oxygen sensor will measure the amount of oxygen produced by the pondweed over time and will display the results on a screen or a graph. The higher the oxygen production, the faster the rate of photosynthesis.
WebTherefore, when the rate of respiration is greater than the rate of photosynthesis, the CO 2, concentration will increase, and pH will fall.
