Unit 1
What is a control group?
The group in an experiment unaffected by the independent variable
What are the three types of organic molecules we studied?
Carbohydrates, Proteins, and lipids
What is the goal of cellular respiration?
Creating ATP (energy)
Wat is the energy molecule used by all living things?
ATP
What is the purpose of the Lysosomes?
They contain enzymes for breaking down nutrients
What is a dependent variable?
What you are measuring
What are enzymes?
Proteins that break apart substances
What do chloroplasts do?
They perform photosynthesis to make glucose.
Which organisms contain mitochondria?
All
What is the pH range of acids?
0-6.9*
What is biology the science of?
Life :D
What happens to enzymes when there is a change in pH or temp?
They unfold and can't function (denature)
In a HYPOTONIC solution, the cell...
expands
How do autotrophs get their food?
They create their own
If you mix a strong acid with an equally strong base, what happens to that substance?
It neutralizes (7 pH)
What is an inference?
An educated guess based on an observation
What are the four elements found in proteins?
Carbon (C), Hydrogen (H), Oxygen (O), and Nitrogen (N)
What are feedback loops?
What is the chemical equation for photosynthesis?
6(CO2) + 6(H2O) → C6H12O6 + 6(O2).
What is a hydrolysis reaction?
What is a dehydration reaction?
Hydrolysis reaction: adds water to polymer chain to break it
Dehydration reaction: removes water from polymer chain to build it
What is an observation?
An act of noting a fact or occurrence through the five senses
Which size categories of carbohydrates tend to be sweet?
Monosaccharides
They are attached to carbohydrate chains which are a type of "name tag" for the cell
How is energy released from ATP?
One of three phosphate groups are broken off, and that releases energy for the body
Why is water considered a polar molecule?
Because the Oxygen is larger that the Hydrogen, causing the Oxygen to share more electrons with the Hydrogen. This unbalances the charge on either side of the molecule.
