An independent variable is the manipulative variable. It is the tested object
What is an independent variable
100
A basic unit of matter
What is an atom
100
Enzymes speed up rate of chemical reactions but not how much product is made. Catalysts decrease the amount of activation energy
Why do we call them enzymes and not just catalyst
100
Proteins, Carbohydrates, Nucleic Acids, and Lipids
What are the four main types of macromolecules.
200
A dependent variable is the responding variable which responds to the manipulated variable
What is a dependent variable
200
Protons- positive and found inside the nucleus Neutrons- no charge and also found inside the nucleus Electrons- negative charge and found outside the nucleus
What are the three types of subatomic particles and where can they be found
200
Active site and substrate
What is the name of the bonding site on an enzyme and what material the enzyme acts on
200
Carbohydrates- Benedicts and Iodine. Benedicts(Cloudy orange) for simple sugars and iodine for starches. Iodine (Dark purple)for complex(starch) Lipids- Sudan III and brown paper bag test- Sudan III turns red and Brown paper bags turns transparent Proteins- Biurets Reagent turns lilace
What are the indicator tests
300
A control group is used for comparison
What is the purpose of a control group
300
The numbers of protons and neutrons in the nucleus
What does atomic number mean
300
Temperature can change the enzyme activity
What can affect the environment of an enzyme
300
Carbohydrates- Monosaccharide's(Monomer) Polysaccharide(Polymer) Lipids- triglyceride ( 1 glycerol and 3 fatty acids) no Polymer. Proteins- amino acids Nucleic acids- Nucleotides
What are the subunits of each macromolecule
400
The variable group are the tested subjects
What is a variable group
400
Isotope-Atoms of the same element that have different numbers of neutrons Ions- An atom that has gained or lost one or more electrons Compounds- A pure substance formed when two or more different elements combine
What does Isotopes, Ions, and Compounds mean
400
Some proteins act as enzymes
How are enzymes related to macromolecules
400
Dehydration Synthesis. Take 2 hydrogen's and 1 oxygen are taken out. (Join together) Hydrolysis- Add the water back in.( Break apart)
How do you join and break apart bonds
500
The two types of data are Quantitative and Qualitative. Quantitative is shown by numbers. Qualitative is shown through pictures, words, or objects
What are the two types of data
500
Electrons decide which part of the atom controls which atoms bond with each other
What decides which part of the atom bonds together
500
energy needed for a chemical reaction
What is activation energy
500
Lipids- provide long term energy, biological membranes, waterproof coverings, and chemical messengers (Steroids) Carbohydrates- Quick Energy, stores energy, structural support, source of carbon. Proteins- Speed up chemical reactions, structural support in humans, transports oxygen, Nucleic acids- store genetic information
What are the functions of each macromolecule
