Calvin Cycle can occur without ATP

• True

• False

What is the Calvin Cycle?

• A complex series of chemical reactions carried out in the stroma.

• is a series of protein complexes that transfer electrons from electron donors to electron acceptors via redox reactions and couples this electron transfer with the transfer of protons across a membrane.

• The cycle of how to make and sell Calvin Klein product

• a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.
