Ch 14: Photosynthesis & Cellular Respiration: Help & Review

About This Chapter

The Cellular Respiration and Photosynthesis chapter of this GED Science Help and Review course is the simplest way to learn about cellular respiration and photosynthesis. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of cellular respiration and photosynthesis.

Who's it for?

Anyone who needs help learning or mastering GED science material will benefit from taking this course. There is no faster or easier way to learn GED science. Among those who would benefit are:

  • Students who have fallen behind in understanding the transformation of energy in living organisms or cellular respiration and photosynthesis processes
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about cellular respiration and photosynthesis
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the cellular respiration and photosynthesis chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the cellular respiration and photosynthesis chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any cellular respiration or photosynthesis question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in a cellular respiration and photosynthesis unit of a standard GED science course. Topics covered include:

  • Redox reactions and electron carriers in cellular respiration
  • The glycolysis pathway
  • The citric acid cycle
  • The electron transport chain
  • Chlorophyll's role in photosynthesis
  • Photolysis and light reactions
  • The Calvin-Benson cycle

12 Lessons in Chapter 14: Photosynthesis & Cellular Respiration: Help & Review
Energy and Life: The Transformation of Energy in Living Organisms

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.

Cellular Respiration: Energy Transfer in Cells

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.

Cellular Respiration in Yeast

3. Cellular Respiration in Yeast

In this lesson, we'll learn about cellular respiration in yeast. Here, we'll cover what yeast is and the two ways that it uses cellular respiration to make energy.

Redox Reactions & Electron Carriers in Cellular Respiration: Definitions and Examples

4. 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.

Glycolysis Pathway: Steps, Products & Importance

5. 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.

The Citric Acid (Krebs) Cycle: Products and Steps

6. 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.

The Electron Transport Chain: Products and Steps

7. 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.

Chlorophyll: Absorbing Light Energy for Photosynthesis

8. 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!

Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products

9. 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.

Dark Reactions of Photosynthesis: The Calvin-Benson Cycle

10. 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.

Acetyl Coenzyme A (Acetyl-CoA): Formation, Structure & Synthesis

11. Acetyl Coenzyme A (Acetyl-CoA): Formation, Structure & Synthesis

In this lesson, you'll learn what acetyl coenzyme A is by discovering its structure and how it's synthesized or formed by the cell. You will further uncover a bit about the function of coenzyme A.

What is Chemiosmosis? - Definition & Process

12. What is Chemiosmosis? - Definition & Process

This lesson is about chemiosmosis, an important process that allows our bodies to make energy. In this lesson, we'll discuss what chemiosmosis is and how it works, and we'll look at some actual applications in the body.
