What type of metabolism are these single celled eukaryotes undergoing? - Practice Question
You have a culture of single celled eukaryotes in an enclosed chamber but you are unsure if they are photosynthetic or not. In order to test this you start by giving the cells glucose in the absence of light and change their culture conditions while simultaneously measuring the carbon dioxide and oxygen concentrations in the chamber. Given the below data, which of the following are true?
