Building Macromolecules Flashcards
Lions and elephants digest their foods by breaking bonds between elements. What elements are found in carbohydrates, lipids, and proteins?
Carbon, Nitrogen (protein only) , Hydrogen, Oxygen
How can organisms build a new macromolecule from the foods they eat?
Break down the bonds between elements & reconstruct them into new macromolecules.
Monomers of carbohydrates (1)
Monosaccharides
monomers of proteins
amino acids
monomers of lipids
glycerol and fatty acids
monomers of nucleic acids
nucleotides
Macromolecule
Giant molecule
Peptide bond
A bond that links two amino acids together
protein functions:
Repair, growth, transporting nutrients, cell communication
carb functions:
provides energy and structure, main source of energy
lipid functions
stores energy, transports nutrients, insulate
what macromolecules do elephants and lions have
lions: proteins and lipids
elephants: proteins and carbs
what element is only found in protein?
nitrogen :OOOO
which has the highest energy potential?
lipids
which is the main source of energy
carbs
fill in the blank: A general rule for processes such as cell respiration is the more _______ atoms there are in a molecule, the more energy that molecule can provide to the organism when it is used as food.
carbon
why are lipids important energy wise
Lipids are used to store energy but most importantly to provide large amounts of energy. This is because it has the highest amount of Carbon. Carbon bonds have a lot of energy so when it breaks during consumption it gives the organism lots of energy.
