Ch 2: Enzymes and Metabolism for the MCAT: Tutoring Solution

About This Chapter

The Enzymes and Metabolism chapter of this MCAT Prep Tutoring Solution is a flexible and affordable path to learning about enzymes and metabolism. These simple and fun video lessons are each about five minutes long, and they teach all of the processes involving enzymes and metabolism required in a typical MCAT prep course.

How it works:

  • Begin your assignment or other MCAT prep work.
  • Identify the enzymes and metabolism concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our MCAT tutoring solution will benefit any student who is trying to learn about enzymes and metabolism and prepare for the exam. This resource can help students including those who:

  • Struggle with understanding enzyme functions and reactions, substrates, electron transport chain or any other enzymes and metabolism topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their enzymes and metabolism unit
  • Cope with ADD or ADHD
  • Want to get ahead in preparing for the MCAT
  • Don't have access to their MCAT instructor outside of class

Why it works:

  • Engaging Tutors: We make learning about enzymes and metabolism simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live MCAT tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about enzymes and metabolism on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives:

  • Review how enzymes function.
  • Learn how enzyme activators and inhibitors regulate reactions.
  • See how factors like pH and temperature affect enzyme activity and structure.
  • Explore the steps of cellular respiration, including glycolysis, the citric acid cycle and the electron transport chain.

Function of Enzymes: Substrate, Active Site & Activation Energy

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

In this lesson, we'll learn how enzymes function to lower the activation energy of a chemical reaction. Enzymes bind to their substrates to perform all kinds of important and essential cellular processes, as well as processes that help you enjoy a slice of pizza!

Enzymatic Reactions: Inhibition and Regulation

2. Enzymatic Reactions: Inhibition and Regulation

Enzymes are generally not allowed to run uncontrolled in a cell. While they are useful in catalyzing reactions, there is a time and place for everything. In this lesson, we'll discuss enzyme activators and inhibitors that regulate these reactions positively and negatively, respectively.

Enzyme Activity & Inhibition: Structure, Substrates, pH & Temperature

3. Enzyme Activity & Inhibition: Structure, Substrates, pH & Temperature

Enzymes appreciate the right working conditions. Can you blame them? We all work best in the correct environment. In this lesson, we'll learn how substrate concentration, temperature, and pH affect enzyme activity and structure.

Lock and Key and Induced Fit Models of Enzyme Activity

4. Lock and Key and Induced Fit Models of Enzyme Activity

Cells are full of chemical reactions, but nature doesn't like waiting any more than we do. Enzymes help speed up these reactions, and over time, scientists have modified their theories on how this works. In this lesson, we'll explore the two main theories that explain this.

The Citric Acid (Krebs) Cycle: Products and Steps

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.

The Electron Transport Chain: Products and Steps

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.

The Metabolism of Fats, Proteins & Carbohydrates

7. The Metabolism of Fats, Proteins & Carbohydrates

Everybody eats. But what happens to that food once it is eaten? Cellular respiration explains carbohydrates, but what about fat and protein? This lesson explores how all three macronutrients are used by the body.

Chemical Digestion of Carbohydrates: Definition & Process

8. Chemical Digestion of Carbohydrates: Definition & Process

Carbohydrates are an important energy source, but must be broken down to be absorbed out of the digestive tract. In this lesson, you will learn how disaccharides and polysaccharides are broken down to monosaccharides through a process called hydrolysis.

Glycolysis Pathway: Steps, Products & Importance

9. 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.

Organic Chemical Reactions: Redox, Esterification & Fermentation

10. Organic Chemical Reactions: Redox, Esterification & Fermentation

There are many different types of reactions that occur in organic chemistry. This lesson will highlight three reactions, explaining which organic molecules are the reactants and which are the products, as well as what occurs during the reaction.

Glycogenesis, Glycogenolysis, and Gluconeogenesis

11. Glycogenesis, Glycogenolysis, and Gluconeogenesis

Your body uses processes to keep blood glucose levels within the normal range. Learn how your body decreases blood glucose levels through glycogenesis and how it boosts glucose levels through glycogenolysis and gluconeogenesis in this lesson.

The Pentose Phosphate Pathway

12. The Pentose Phosphate Pathway

There are hundreds of various chemical reactions that occur within cells. In this lesson, we are going to check out one of those reactions, called the pentose phosphate pathway. Let's see what this reaction is, as well as what it produces and why it's important.

Substrate-level Phosphorylation and Oxidative Phosphorylation

13. Substrate-level Phosphorylation and Oxidative Phosphorylation

Your body is always using energy. This energy, in the form of ATP, is generated within your cells through substrate-level phosphorylation or oxidative phosphorylation. Learn about these processes and the role mitochondria play in making energy.

Anabolism: Definition & Examples

14. Anabolism: Definition & Examples

In this lesson, you will learn about anabolism, how it occurs in the body, and the importance of it. Also, we will take a look at an example of anabolism.
