About This Chapter
Cellular Respiration & Photosynthesis - Chapter Summary
In the lessons on cellular respiration, you will rediscover how carbohydrates, lipids and proteins are converted into energy at the cellular level. You will examine both aerobic and anaerobic respiration, how they differ and the steps involved in both reactions.
The lessons covering photosynthesis illustrate energy transfer in plants, the Calvin-Benson cycle, the importance of chlorophyll and more. The material contained in the lessons includes the following:
- Energy transformation in living things
- Process of cellular respiration and redox reductions
- Steps and significance of the glycolysis pathway
- Products and steps of the Krebs Cycle and electron transport chain
- Role of chlorophyll in photosynthesis
- Light and dark reactions in photosynthesis
The video lessons in this study guide are accompanied by fully written transcripts that set off specialized terminology and key vocabulary in bold text to make identification and reference easy. Each video includes a timeline feature that allows you to skip sections you don't want to view, replay sections you want to see over again, and go directly to particular parts of a video without replaying the lesson from the beginning. A short quiz tests for retention, and the dashboard provides a handy place to store your work.
1. Energy and Life: The Transformation of Energy in Living Organisms
While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.
2. Cellular Respiration: Energy Transfer in Cells
Watch this short video to learn the basics about converting organic compounds into ATP, also known as cellular respiration. We'll look at an overview of the process.
3. Redox Reactions & Electron Carriers in Cellular Respiration: Definitions and Examples
Redox reactions play an important role in cellular respiration. In this lesson, you will see how NAD and FAD are used as electron carriers to temporarily store energy during cellular respiration.
4. Glycolysis Pathway: Steps, Products & Importance
Cellular respiration creates chemical energy in the form of ATP from the food we eat and the air we breathe. In this lesson, we'll learn about the first part of this process, glycolysis.
5. The Citric Acid (Krebs) Cycle: Products and Steps
In this lesson, we return to the process of cellular respiration for the second act of creating energy from food. In this act, products from glycolysis feed into the next stage, the citric acid cycle.
6. The Electron Transport Chain: Products and Steps
In this lesson, we'll learn about the finale of cellular respiration. The electron transport chain uses products from the first two acts of glycolysis and the citric acid cycle to complete the chemical reaction that turns our food into usable cellular energy.
7. Chlorophyll: Absorbing Light Energy for Photosynthesis
Plants are clean, green, photosynthesizing machines. Using a specialized pigment called chlorophyll, plants are able to soak up energy from the sun and turn it into food. In this lesson, we'll start to learn why chlorophyll literally gets excited about a sunny day!
8. Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products
In this lesson, we'll learn how electrons get excited during the light-dependent reactions of photosynthesis, jumping off photosystem reaction centers like they were trampolines! In addition, we'll learn how the splitting of water creates reactants for this part of photosynthesis while creating a little fresh air for us.
9. Dark Reactions of Photosynthesis: The Calvin-Benson Cycle
Photosynthesis starts out using the energy from sunlight to get things started, but it ends with the dark reactions, which don't need sunshine to complete sugar production. In the Calvin cycle, ATP and NADPH from the light reactions are used to produce sugars.
