Unit 2 Concepts Flashcards
What are Macromolecules?
large organic molecules (meaning they contain carbon) used for various functions in living things
Type of Macromolecules
Carbohydrates
Lipids
Proteins
Nucleic Acids
Carbohydrates
Main Function = short-term ENERGY
Other uses = structure/support
Found in: sugar and starch (therefore breads, pastas, fruits and veggies)
Lipids
Main Function = Long-term Energy Storage
Other uses = cushioning organs, insulation, hormones, cell membranes
Found in: Fats, oils, phospholipids (in the cell membrane), steroids
Protein
Most diverse macromolecule
Most abundant macromolecule (make up 50% of cell’s biomass)
They literally RUN your body!!
Nucleic Acids
Main Function: store & transmit hereditary or genetic information
Ex. DNA, RNA
You get them from your PARENTS not your food!
Four Main Types of Monomers
sugars, amino acids, fatty acids, and nucleotides
Three part of a neucleotide
5-carbon sugar
Phosphate group
Nitrogenous base
What is the main energy source for organisms?
Food
Main function of a carbohydrate
Short Term Energy
Main function of a protien
Long Term Energy
Main function of a lipids
Long Term Energy Storage
Main function of a neucleic acids
store & transmit hereditary or genetic information
What are examples of lipid polymers?
fats, oils, phospholipids, steroid, hormones
What does an enzyme do?
Controls rate of chemical reaction
Enzymes reduce energy needed (activation energy) to start a chemical reaction and increases reaction rate.
What category of macromolecules is an enzyme?
protien
How does an enzyme work?
They are catalysts, or substances that control how quickly chemical reactions occur.
Main purpose of photosynthesis
is converting radiant energy from the sun into chemical energy in the form of glucose.
What is energy transformation in photosynthesis?
Where in cell does photosynthesis occur?
Chloroplast
What types of organisms perform photosynthesis
plant
What is chlorophyll
what makes the leaves green
What is the function of chlorophyll
function of chlorophyll is to capture the light energy of the sun and convert water and carbon dioxide to produce glucose and oxygen.
What is light energy from the sun used for in photosythesis?
uses energy to convert water and carbon dioxide to glucose and oxygen
Name the Blank Labels
A - Light
B - H2O
C - C2O
D - O2
I - Glucose
What are the 2 stages of photosynthesis called?
Light Dependent and Light Independent
Where do the 2 stages of photosynthesis occur in the chloroplast?
Light Dependent occurs in the thylakoid membrane… Light Independent occurs stroma the region outside of the thylakoids
In photosythnesis what is the source of oxygen produced…
water
What is the major waste product given off from photosynthesis
oxygen
