The cell diagrammed below provides an overview of some regulation of the Calvin cycle. Which of the following is NOT involved in this regulation? CO2 and HCO3−− . b. CO2 and HCO3−− are sequestered inside a carboxysome. c. Rubisco is sequestered inside a carboxysome. d. Carbonic anhydrase is used to convert CO2 to HCO3− and thus trap it. e. Proteins are used to block light and thus the light reactions." class="answers-bank-image d-block" loading="lazy" > a. Several different transport mechanisms are used for CO2 and HCO3−− . b.
