Carbon dioxide is a ______ in photosynthesis and a ________ in cellular respiration.
Glucose (sugar) is a______ in photosynthesis and a in cellular respiration.
Carbon dioxide is a reactant in photosynthesis and a product in cellular respiration.
To understand this, let's break it down:
1. In photosynthesis:
During photosynthesis, plants and other photosynthetic organisms use carbon dioxide, along with water and sunlight, to produce glucose (sugar) and oxygen. Carbon dioxide acts as a reactant, meaning it is one of the starting materials that participates in the reaction. In this process, carbon dioxide is converted into glucose.
2. In cellular respiration:
During cellular respiration, organisms break down glucose and convert it into energy usable by the cell. In this process, oxygen is used as a reactant, and carbon dioxide is produced as a waste product. This means that carbon dioxide is a product, meaning it is one of the resulting substances produced by the reaction.
So, to summarize:
- In photosynthesis, carbon dioxide is a reactant.
- In cellular respiration, carbon dioxide is a product.
Additionally, glucose (sugar) is a product in photosynthesis and a reactant in cellular respiration.
Hope that helps clarify the roles of carbon dioxide and glucose in both photosynthesis and cellular respiration!
