Properly wrapped, salted butter will keep in the freezer for up to one year. After this, it may begin to lose the fresh butter flavour and pick up other odours or flavours from the freezer. Unsalted butter will keep in the freezer for up to three months. Stay Connected.
Light-independent reactions take place in plant chloroplasts. In this process sugars are made from carbon dioxide. The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATP and NADPH) and various enzymes.
The process of photosynthesis involves two main phases of reactions: the light reactions, those that require light energy, and the Calvin cycle, which is the light-independent stage. The main reaction during the light-independent reaction is the conversion of carbon dioxide into organic molecules.
