In this video, we cover: - What enzymes are - How enzymes work - The difference between the lock and key model and the induced fit model Exam board specific info: AQA - Suitable for everyone IGCSE Edexcel - Suitable for everyone Edexcel...

This video covers: - How temperature affects enzymes and the rate of reaction - How pH affects enzymes and the rate of reaction - Why enzymes denature - Was optimum temperature and optimum pH mean

Learn how we digestive enzymes such as amylase, proteases and lipases to break down carbohydrates, proteins and lipids. We also cover where the enzymes are made and what they break each food group down to.

It introduces enzymes as the biological catalyst. It also describes their chemical structure, types, nomenclature and mechanism of action.

Factors Affecting Enzyme Function explains how changes in pH, temperature, and concentration levels can affect enzyme function.

Have you ever wondered why pineapples sting your tongue? It's because they contain an enzyme called bromelain, which can break down proteins. This means that every time you eat a pineapple, it eats a little bit of you! In this video we...

Short answer: Yes, drinking a lot of water will certainly change the pH of the stomach, but this amount is trivial. However, since your stomach is very acidic, to begin with, drinking water will not dilute it significantly. Also, there...

In this video, we explore beta-oxidation, its mechanism, and what it produces.

This video is a lecture presentation on the process of genetic engineering. The presenter describes and discusses the steps involved in modifying the genome of a bacterium cell, and then evaluates some of the uses and...

In this video, we will discuss the general isoprenoid biosynthesis and processing pathways and how statin medications fit into the big picture (e.g., HMG-CoA Reductase). We will see how statins disrupt Coenzyme Q and vitamin D synthesis.
