Ch 19: Energy Transfer in Organisms

About This Chapter

Energy transformation is an important process in cellular function. Use this short chapter to boost your understanding of or learn new facts about this topic as you prepare for relevant school tests or even teacher certification exams.

Energy Transfer in Organisms - Chapter Summary

This chapter is designed to teach you most of the basic details that you must understand about energy transfer in organisms as you prepare for lectures, tests or professional exams. You can expect to find lessons devoted to such topics as photosynthesis, cellular respiration and transpiration.

You will also learn about the importance of feedback mechanisms and the process by which energy from the sun is transformed into potential energy. When you have finished reviewing this chapter, you should be able to:

  • Discuss the transformation of energy from the sun and other sources in living organisms
  • Define photosynthesis
  • Explain transpiration in plants
  • Detail the process of cellular respiration
  • Understand and use equations for aerobic cellular respiration and anaerobic respiration
  • Provide details about the uses of feedback systems in organisms

The lessons in this chapter allow you to study when it's most convenient for you with 24/7 access from any device. Use your Dashboard to track your progress as you move from one lesson to the next. Measure your knowledge with short self-assessment quizzes you can take after you review each lesson.

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.

Photosynthesis: Definition & Reactions

2. Photosynthesis: Definition & Reactions

Some people may falsely assume plants to be weaker than animals. However, plants and a few other organisms harness light energy from the sun to feed the rest of us. This lesson will introduce you to how they do it.

What Is Transpiration in Plants? - Definition, Rate & Process

3. What Is Transpiration in Plants? - Definition, Rate & Process

Did you know that plants 'sweat?' Transpiration is both an important and costly process for plants, and it requires that a delicate balance between it and other necessary cellular processes be maintained.

Cellular Respiration: Energy Transfer in Cells

4. 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.

Aerobic Cellular Respiration: Stages, Equation & Products

5. Aerobic Cellular Respiration: Stages, Equation & Products

Aerobic cellular respiration is the process in which our cells break down food and turn it into energy that cells need to perform their life functions. This lesson goes through the process, formula, and end results of aerobic cellular respiration.

Anaerobic Respiration: Definition, Equation & Examples

6. Anaerobic Respiration: Definition, Equation & Examples

Many organisms are capable of undergoing anaerobic respiration. In some cases, it's a 'backup plan' when oxygen is absent, and in other cases, they thrive that way. Here we will investigate what anaerobic respiration is, the equation and examples of it at work.

Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis

7. Using Feedback Systems to Regulate Growth, Reproduction & Dynamic Homeostasis

In order to maintain specific internal conditions, organisms use feedback mechanisms. Feedback is essential to the regulation of internal environments, which allows for proper biological functioning.
