Biochemical Reactions: Synthesis and Decomposition

1. Biochemical Reactions: Synthesis and Decomposition

In biochemical reactions, substances react to one another to produce a product. Explore more about the different types of biochemical reactions, including synthesis reactions, decomposition reactions, and reversible reactions.

Function of Enzymes: Substrate, Active Site & Activation Energy

2. Function of Enzymes: Substrate, Active Site & Activation Energy

Enzymes are proteins that lower the activation energy of a reaction and act as a catalyst in living organisms. Learn more about the concepts of activation energy, substrate, enzyme-substrate complex, and active site, and discover their connection to the structure and function of enzymes.

Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions

3. Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions

Enzymes sometimes require partners, called coenzymes, to function. Learn about two other aspects of enzyme function, including cofactors and prosthetic groups, each of which has different functions and interacts with enzymes differently.

Enzymatic Reactions: Inhibition and Regulation

4. Enzymatic Reactions: Inhibition and Regulation

Enzymes can be regulated positively by activators or negatively by inhibitors. Explore more examples of enzyme activity regulation, competitive inhibition, and non-competitive inhibition.

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

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

Cellular respiration is an important process that helps organisms produce energy. Learn about the definitions of redox reactions and electron carriers, including NAD and FAD, in cellular respiration, and find an example of the basic formula that describes the process.

Cellular Respiration: Energy Transfer in Cells

6. Cellular Respiration: Energy Transfer in Cells

Cellular respiration is an important process that enables all living organisms to convert organic compounds into energy. Learn about cellular respiration and understand the roles of adenosine triphosphate, adenosine diphosphate, and oxygen to perform energy transfers in cells.

Glycolysis Pathway: Steps, Products & Importance

7. Glycolysis Pathway: Steps, Products & Importance

Glycolysis is the first step in cellular respiration, which is the final step in the process of converting food to chemical energy. Learn more about the steps of the glycolysis pathway and the importance of molecules and other products used in the process.

Lactic Acid & Alcoholic Fermentation: Comparison, Contrast & Examples

8. Lactic Acid & Alcoholic Fermentation: Comparison, Contrast & Examples

The production of lactic acid from cells in the human body is similar to how fermentation produces alcohol from yeast. Learn about the process of aerobic cellular respiration, and compare and contrast the production of lactic acid and the fermentation of alcohol.

The Citric Acid (Krebs) Cycle: Products and Steps

9. The Citric Acid (Krebs) Cycle: Products and Steps

The citric acid cycle is the second of a three-part process of cellular respiration. Explore how our bodies progress from the first stage, glycolysis, and through the citric acid cycle before reaching the electron transport chain as food is transformed into energy.

The Electron Transport Chain: Products and Steps

10. The Electron Transport Chain: Products and Steps

The third step in the cellular respiration process is called the electron transport chain. Learn about cellular respiration and how the electron transport chain uses the products of glycolysis and the citric acid cycle to complete the final steps in the process and convert food into energy.
