Enzymes are specialized biological molecules that act as catalysts, dramatically speeding up chemical reactions by lowering the activation energy needed. Think of them as tiny molecular machines that help your body function efficiently.
These remarkable molecules perform several critical functions in living organisms. They enable essential processes like digestion (breaking down food into usable nutrients), metabolism (chemical reactions that sustain life), and vital cellular functions that keep your cells working properly.
Enzymes also play crucial roles in energy production, helping release energy from the food you eat through processes like cellular respiration. They're involved in your immune response, assisting with functions like blood clotting and inflammation when you're injured.
Quick Fact Without enzymes, many biological reactions would happen too slowly to support life! A reaction that might take years can happen in milliseconds with the right enzyme present.
Enzymes have a special region called the active site where substrates (the molecules being acted upon) bind. When a substrate enters this active site, the enzyme changes shape slightly to fit it perfectly, forming an enzyme-substrate complex. After the reaction occurs, the products are released, and the enzyme returns to its original state.
Enzyme activity can be blocked through several types of inhibition. In competitive inhibition, molecules compete with the substrate for the active site, temporarily slowing enzyme activity. With non-competitive inhibition, inhibitors bind elsewhere on the enzyme, changing its shape and reducing efficiency.
Reversible inhibition is temporary and can be overcome when the inhibitor is removed. In contrast, irreversible inhibition permanently deactivates enzymes by forming strong bonds that cannot be broken, completely stopping their function.
Remember The lock-and-key or induced fit model helps explain enzyme specificity - enzymes are highly selective about which molecules they interact with!
Enzymes and coenzymes work together but have distinct differences. Enzymes are large protein molecules that remain unchanged during reactions and are highly specific to particular reactions. Coenzymes, however, are smaller non-protein compounds that bind to enzymes' active sites, change during reactions, and are less specific.
Multiple factors affect how well enzymes work. Temperature significantly impacts enzyme activity - reactions speed up with increasing temperature until reaching an optimum point, after which enzymes denature and lose function. Similarly, each enzyme has an optimum pH where it works best.
Enzyme concentration affects reaction rates too - more enzyme generally means faster reactions, as long as enough substrate is available. Likewise, increasing substrate concentration speeds up reactions until all enzyme active sites are occupied, creating a plateau in reaction rate.
Study Tip Think about enzyme factors like Goldilocks - conditions need to be "just right" for optimal enzyme function!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
