Nature of Matter
This determines the identity of an atom.
What is the number of protons?
This macromolecule provides quick energy.
What are carbohydrates?
Catalysts lower this.
What is activation energy?
This cycle includes evaporation, condensation, and precipitation.
What is the water cycle?
The monomer of carbohydrates is called this.
What is a monosaccharide?
These three particles make up atoms.
What are protons, neutrons, and electrons?
This macromolecule stores long-term energy and makes up cell membranes.
What are lipids?
Enzymes are important because they do this to reactions.
What is speed them up?
These processes release water into the atmosphere.
What are evaporation and transpiration?
An athlete needs immediate energy before a race. Which macromolecule should they consume and why?
What are carbohydrates because they provide quick energy?
This part of the atom contains protons and neutrons
What is the nucleus?
These are long chains of amino acids.
What are proteins?
This stype of enzyme connects two substrates to make one product.
What is an anabolic enzyme?
Groundwater is stored in this underground structure.
What is an aquifer?
This acronym represents the six most important elements in biological molecules.
What is CHNOPS?
Changing this particle changes the element’s name.
What are protons?
This macromolecule stores and transfers genetic information.
What are nucleic acids?
This molecule that binds to the enzyme’s active site.
What is the substrate?
These organisms break down wastes and dead organisms in the carbon cycle.
What are decomposers (bacteria and fungi)?
If global temperatures rise, increased decomposition could create a feedback loop by increasing this atmospheric gas.
What is carbon dioxide?
This type of particle has a positive charge and is located in the nucleus.
What is a proton?
This is the monomer of proteins.
What is an amino acid?
When temperature or pH changes the shape of an enzyme, this occurs.
What is denaturation?
This process fixes carbon from the atmosphere into usable form.
What is photosynthesis?
Increasing atmospheric CO₂ contributes to this global environmental issue.
What is global warming (climate change)?
