BIOLOGY 172 Lecture Notes - Lecture 16: Deoxyribonuclease, Sulfur, Dna Polymerase
Document Summary
In photosynthesis, you start with two linked reaction: photo reactions (light reactions where you use light energy and water and produce oxygen, atp, and. Nadph) and synthesis reaction that takes place in the stroma of the chloroplast (dark reactions also known as the calvin cycle where carbon dioxide is fixed and put it into a form in which all cells can use it). The molecule that we get out of the calvin cycle is the g3p molecule. The first step: is taking carbon dioxide and linking it to a 5 carbon molecule called. This is called carbon fixation and is done by the enzyme rubisco. This enzyme is the source of most of the carbon fixation on earth. In photosynthesis, rubisco takes the rubp (a 5 carbon molecule) and links it with a carbon dioxide to produce a molecule called 2,3-phosphoglycerate that is used in the calvin cycle.
