Which is a reactent in the calvin cycle?
a. CO2
b. C6H12O6
c. h2o
d.02

a. CO2

Explanation: CO2 fixation is the first step in the Calvin cycle. Calvin cycle is driven by the products of the light reactions of photosynthetic carbohydrate synthesis. CO2 is a product of the light reactions. In the fixation of CO2, three molecules of CO2 is incorporated into three molecules of ribulose 1, 5-bisphosphate (5 carbon sugar) to form six molecules of 3- phosphoglycerate (3 carbon molecule). This reaction is catalyzed by an enzyme known as ribulose 1, 5- bisphosphate caboxylase (rubisco).

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
