Anabolic
Protein
Catabolic
When an atom loses an electron, it becomes __.
An anion
A cation
A carbon
A Nucleus
Which macromolecule is broken down first for energy?

Carbohydrates
What phenomenon is being shown in this diagram?
Capillary Action
Meniscus
Surface Tension
Ionic Bonding
What property of water is being shown in this picture?
Universal Solvent
Cohesion/Adhesion
Less Dense when Frozen
Specific Heat
In your Acids & Bases lab, the dependent variable is __.
The one you measure
The one you changed/tested
The whole group of constant variables
False, there is no such thing as a dependent variable.
What was my favorite number?
(a)
If the __ of a protein changes, so will its function.
Substrate
Nucleotide
Shape
Product
Sweating is __.
A response to your environment.
Something Canadians do
A part of your metabolism.
An example of growth & development.
Which of the following is a reason why water being a universal solvent is important for all life?
It can regulate body temperatures.
Chemical reactions require the nutreints to be dissolved into the blood.
Plants can get water from its roots to its trees.
It prevents lakes and oceans from freezing solid.
Why are electrons involved in bonding instead of protons/neutrons?
Ionic bonds form when an atom takes an electron from another atom.
They don't, protons are what form bonds.
Electrons are what form hydrogen bonds.
Electrons surround the nucleus making it easier for them to interact with the electrons of other atoms.
Which type of molecule will your body break down first?
Protein
Carbohydrate
Lipid
Nucleic Acid
Based on this animation, would the reaction take place?
42
Absolutely not
Of course it would
No, its from Canada.
Based on the animation, if the result of the reaction was two products, we could say this reaction was __.
Anabolic
Ionic
Covalent
Catabolic
