Question

to identify the molecule that first reacts with co2 in the light-independent reactions of photosynthesis, calvin and benson manipulated the carbon-fixation cycle by either elminating co2 or light from cultures of photosynthetic algae. which of the following statements best predicts the immediate effects of these manipulations on the concentration of the molecule that initially reacts with co2?

Answer 1

The awareness could growth whilst the CO2 is eliminated, however lower whilst the mild is eliminated is the statements best predicts the effects of manipulations on concentration of molecule that initially reacts with co2.

Elevated [CO2] will increase the supply of carbon in leaves inflicting extra Rubisco pastime and better costs of photosynthesis. Greater photosynthesis will increase the content material of non-structural carbohydrates in leaves that may result in extra starch reserves and expanded auxin biosynthesis.In spring, flowers withinside the Northern Hemisphere start to develop and soak up CO2 from the atmosphere, so atmospheric CO2 awareness decreases—the road dives down.

In fall, flowers start to decay and launch their CO2 returned into the atmosphere, so atmospheric CO2 awareness will increase—the road shoots up.
