Important notes
A hydrogen bond is an attraction between a a positive hydrogen and negative atom
A water molecue is 2 hydrogen atoms + 1 oxygen atom
A monomer is a tiny piece of molecule that can join with other molecules to make bigger molecules
A macromolecule is a MASSIVE molecule made up from other molecules
The four big macromolecules: Lipids, Nucleic Acids, Proteins and Carbohydrates
is a carbohydrate polymer or hydro
A carbohydrate is a type of macromolecule that your body can use for energy.
Think of carbohydrates as fuel for your body. ⛽⚡
🧫 Transmembrane — ADHD-friendly
Transmembrane means:
“Going across a cell membrane.”
Break the word apart:
Trans = across
Membrane = the cell's outer barrier
ATOM → MOLECULE → MACROMOLECULE (molecules are made of atoms, not the other way around)
We are made up of millions of cells, particles that each have a job to do, the basic unit of life
ATP stands for adenosine triphosphate.
ATP is the cells usable energy, so it is to help cells do their job and provides energy to the cells
ATP is the cell's usable energy. It provides energy to help cells do their jobs.
A monomer is a small molecule that can chemically bond with other similar or identical molecules to form a larger chain or network called a polymer
Macromolecule | Basic job in the cell | 🧠 Think |
|---|---|---|
🍞 Carbohydrates | Provide quick energy | ⚡ Fuel |
🧈 Lipids (fats) | Store energy and help make cell membranes. They also help make up the cell membrane. | 🔋 Storage + protection |
🥩 Proteins | Do many jobs in the cell, including building, transporting, and speeding up reactions | 🛠 Workers |
🧬 Nucleic acids | Store and carry genetic information. the instructions that tell your cells how to build and run your body. | 📖 Instructions |
joining two monosaccharides together via a dehydration reaction creates a - A disaccharide (or double sugar)
what type of reaction occurs during synthesis of macromolecules - dehydration synthesis
hydrolysis reaction = reaction that breaks the bonds holding monomers together
which of the following is a type of carbohydrate made of one ring which can be used to construct other carbohydrates - monosaccharide
