1 Symlin Pen is given as an injection under the skin, usually in the stomach area or upper thigh. Do not inject Symlin Pen into the arm, because it may not absorb properly. Rotate injection sites so you do not use the same site repeatedly.  Do not transfer medicine from the pen-injector into a syringe.
These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Despite its name, this process occurs only when light is available. Plants do not carry out the Calvin cycle by night.
How are the dark reactions that occur in plants dependent on the light reactions? a. The chemical energy used in the dark reactions is produced in the light reactions. b. The light reactions produce the oxygen necessary for the dark reactions to proceed. c. Light energy absorbed during the light reactions is used directly in the dark reactions. d. During the light reactions, carbon dioxide is converted to sugars, which are used during the dark reactions.
