Macromolecules
Which macromolecule can be saturated or unsaturated?
A lipid
Activation energy is the amount of energy it takes for what to happen?
What is For a reaction to start
What do enzymes do to chemical reactions?
Proteins
What are the eight characteristics of life?
Reproduce, cells, homeostasis, energy, growth and development, genetic code, evolve, respond to stimuli
Which macromolecule contains genetic information?
Nucleic Acids
What macromolecule is water-proof and can be waxy or slippery feeling?
lipids
What happens to an enzyme if its shape changes?
It won't work anymore
What type of macromolecules can be found in a banana?
carbohydrate (simple sugar) and nucleic acids
What is homeostasis?
A body's maintenance of an internal balance; Ex: sweating, shivering, your body telling you that you need water or food
The function of which macromolecule is to provide the body with immediate energy?
Carbohydrate
What is the name of the molecule that binds to an enzyme?
A substrate
Where does the a substrate bind to an enzyme?
The active site
How are activation energy and the rate of a reaction related?
Enzymes lower the amount of energy needed to begin a reaction (activation energy) and this increases the speed (rate) of a reaction
Which characteristic of life explains why you pull your hand away after getting scratched by a cat?
response to stimuli (reacting to your environment)
Which macromolecule stores and transmits genetic information?
What is Nucleic Acids
A protein is a large polymer. What monomers make up proteins?
amino acids
If something ends in -ase, what does it likely mean about that substance?
It is most likely an enzyme
What is the difference between an independent variable and a dependent variable?
Independent = the one thing you change in an experiment
Dependent = the results of the experiment; this is caused by the independent variable
What three elements make up carbohydrates?
Carbon, Hydrogen, and Oxygen
Which macromolecule includes examples such as pasta, potatoes, sugar, and starches?
What is Carbohydrates
What monomers join together to make up DNA?
nucleotides
What does an enzyme do to the activation energy of a reaction?
What is it decreases the activation energy
The reactants that an enzyme can act upon is called?
What is a Substrate
What is the difference between qualitative data and quantitative data?
Qualitative = observations made with your senses (sight, taste, touch, sound, smell)
Quantitative = observations that can be measured
