Cell Energy Worksheet
Answer the following questions:
What is cellular respiration and what are its three stages?
Cellular respiration is the complete cycle of a glucose molecule that happens to be using oxygen. The three stages of cellular respiration are: Glycosis, the Krebs cycle, and the electron transport chain.
What is the role of glycolysis? Include the reactants and the products. Where does it occur?
Glycolysis is the first stage in cellular respiration. Glycolysis occurs in the cytoplasm also. Glucose is converted and then passed onto the Krebs cycle.
What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur?
The citric acid cycle is also known as the Krebs cycle. This is the second stage in cellular respiration. The role of the citric acid cycle is to break down acids and transfer energy to the electron transport chain.
What is the role of the electron transport system? Include the reactants and the products. Where does it occur?
The role of the electron transport chain is to produce electrochemical proton across the membrane. This is the third stage in cellular respiration and it occurs in the mitochondria.
What is the overall goal of photosynthesis?
- The purpose of photosynthesis is to produce energy for the plants to live on.
Because photosynthesis only occurs in plants, why is it essential to animal life?
- It works in a food chain. The animals eat the plants. If the plant doesn’t go through photosynthesis then the plant will die, eventually killing off all forms of life.
What is the role of the light reactions? Include the reactants and the products. Where does it occur?
The main role of light reactions is to collect energy over a broad Verizon and convert it into energy. This is part of photosynthesis and it occurs in the stroma and the mitochondria.
