How do baking a cake relate to the two stages of photosynthesis?

Answer 1

Light reactions occur mostly in the thylakoid stacks of the grana. Here, sunlight is converted to chemical energy in the form of ATP (free energy containing molecule) and NADPH (high energy electron carrying molecule). Chlorophyll absorbs light energy and starts a chain of steps that result in the production of ATP, NADPH, and oxygen (through the splitting of water). Oxygen is released through the stomata. Both ATP and NADPH are used in the dark reactions to produce sugar.

Light reactions would be like baking the cake itself in the oven.

Dark reactions occur in the stroma. Carbon dioxide is converted to sugar using ATP and NADPH. This process is known as carbon fixation or the Calvin cycle. Carbon dioxide is combined with a 5-carbon sugar creating a 6-carbon sugar. The 6-carbon sugar is eventually broken-down into two molecules, glucose and fructose. These two molecules make sucrose or sugar.

Dark reactions would like be preparing cake batter, and mixing the ingredients.

Answer 2

Baking a cake involves combining ingredients and baking to create a final product. In photosynthesis, the light-dependent stage involves capturing solar energy and converting it into chemical energy, while the light-independent stage (Calvin cycle) uses that energy to produce glucose from carbon dioxide. Both processes involve converting raw materials into a final product through a series of steps.
