enzymes are proteins that speed up chemical reactions by lowering the activation energy required to start them off
the pancreas produces digestive enzymes
The Calvin cycle uses the hydrogen ions and electrons produced by the light-dependent reactions to convert carbon dioxide and water into glucose.
digestion is the process where food molecules are broken down into smaller units so they can be absorbed across cell membranes
Chromoplasts store excess light energy as starch in plant leaves and roots.
mechanical digestion involves physical breakdown of large particles using teeth, tongue, saliva and stomach muscles

chemical digestion uses enzymes produced by glands in the mouth, stomach and small intestine to break down complex carbohydrates, fats and proteins into simpler sugars, fatty acids and amino acids respectively

The Calvin cycle is also known as the dark reaction because it occurs without sunlight.
in plants, photosynthesis takes place in chloroplasts which contain chlorophyll (a green pigment)
In the Calvin cycle, ATP and NADPH molecules from the light-dependent reactions are used to reduce CO2 to form G3P (glyceraldehyde 3 phosphate).
In plants, chlorophyll absorbs most strongly at wavelengths around 430 nm (blue) and 662 nm (red).
