AS Biology - Enzymes topic. Explanation of competitive inhibitor and non-competitive inhibitor and how they affect Vmax and Km when you change the substrate concentration.
WOW! The way you explain the concepts is just amazing. Love the style of your videos- short, concise slow and informative. I was looking everywhere to find some info about this topic as it is quite hard but you explained it in a jiffy. Hope you start making more videos on AS Biology!😃😃😃
I've been so stumped the past hour trying to understand why Vmax is the same whether or not a competitive inhibitor is present and this really helped clarify things for me so much! Thank you !!!!
Binding of non-competitive inhibitors does not interfere with the binding of the substrate, rather it induces a conformational change that makes the enzym worse at catalysing the reaction, thus rendering the enzym basically useless. Therefore, sence you have less working enzym, your Vmax decreases, but sence the binding of substrate to active site is not altered, the Km stayes the same.
