Cell Energy Worksheet

Answer the following questions:

Cellular respiration:

• What is cellular respiration and what are its three stages?

It’s the process to produce energy to survive.

3 stages are glycolysis, Krebs cycle, electron transport chain

• What is the role of glycolysis? Include the reactants and the products. Where does it occur?

This is a sugar process that can happen with or without oxygen

• What is the role of the citric acid cycle? Include the reactants and the products. Where does it occur?

This happens after the glycolysis cycle and then the coenzyme A removes the carbon skeleton to another carbon molecule which produces carbon dioxide.

• What is the role of the electron transport system? Include the reactants and the products. Where does it occur?

The way glycolysis are simple glucoses it helps break down the enzymes into half glucoses.

Photosynthesis:

• What is the overall goal of photosynthesis?

This is for planets have to absorb energy and they have to have it to grow.

• Because photosynthesis only occurs in plants, why is it essential to animal life?

This has to happen for planets to live and provide for the food chain

• What is the role of the light reactions? Include the reactants and the products. Where does it occur?

The carbon dioxide, water, and energy from sun light form glucose and oxygen this happens in the thylakoid membrane.

• What is the role of the Calvin cycle? Include the reactants and the products. Where does it occur?

It reduces power and then makes sugar. Reactants: ATP, NADPH2, CO2, Products: Glucose, Oxygen it can happen any time cause it does not need light

Summary:

• Explain how photosynthesis and cellular respiration are linked within ecosystems.

Photosynthesis and cellular are processes that provide energy for cells and organisms. Photosynthesis is food, energy making process. Cellular is energy using process.
