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.
Light-Dependent Reactions: light is absorbed by the photosystems in the thylakoid membranes and electrons flow through electron transport chains. Light-independent Reactions: consist of the Calvin cycle, which actually produces sugar and uses the ATP formed during light reactions.
