Properties of Water and Macromolecules in Biochemistry- A comprehensive exploration of fundamental biological concepts and their molecular... Show more
Water exhibits unique properties that make it essential for life processes. These properties arise from its molecular structure and hydrogen bonding capabilities.
Definition Cohesion is the attraction between water molecules due to hydrogen bonding, while adhesion refers to water's ability to attract different substances.
Example Surface tension, resulting from cohesion, enables insects to walk on water and allows rocks to skip across ponds.
Highlight Water's unique density properties cause ice to float, as it becomes less dense when frozen, unlike most other substances.
Vocabulary Vaporization refers to the energy required to convert liquid water to gas, contributing to water's temperature stability.
Macromolecules are essential biological compounds composed of smaller building blocks called monomers. These large molecules form the structural and functional basis of life.
Definition Polymers are large molecules composed of many repeating subunits called monomers.
Example Carbohydrates, with a 121 ratio of carbon, hydrogen, and oxygen, typically form ring structures.
Highlight Carbohydrates serve as the main source of short-term energy in biological systems.
These complex molecules serve crucial roles in cellular structure and function, energy storage, and biological processes.
Definition Lipids are non-polar molecules that serve as long-term energy storage and cellular membrane components.
Example Proteins function as antibodies, enzymes, and structural components in living organisms.
Highlight Proteins contain amino acids as their building blocks, incorporating carbon, hydrogen, oxygen, and nitrogen.
The final components of biological systems include specialized proteins and genetic material.
Definition Enzymes are biological catalysts that accelerate chemical reactions by lowering activation energy.
Example DNA and RNA are nucleic acids that store and transmit genetic information.
Highlight Nucleic acids are composed of nucleotides and contain the elements CHON (Carbon, Hydrogen, Oxygen, Nitrogen).
The fundamental aspects of living organisms are defined through specific characteristics that distinguish them from non-living matter. These characteristics form the foundation of biological systems and processes.
Definition Homeostasis refers to the maintenance of stable internal conditions within an organism, such as body temperature and pH balance.
Example A plant cell demonstrates organizational structure, representing the basic unit of life.
Highlight Reproduction occurs in two main forms asexual reproduction involving a single parent, and sexual reproduction requiring both male and female sex cells.
Vocabulary Metabolism encompasses all chemical reactions within an organism that facilitate energy acquisition and utilization.

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
