chapter 3 Flashcards
how is a polymer formed from multiple monomers
dehydration synthesis, removal of OH group and hydrogen atom
why are carbohydrates important for energy storage
c-h bonds store energy
plant cells store energy in the form of ______ animals in the form of _____
starch, glycogen
which sugar is a part of RNA
ribose
a molecule of DNA or RNA is a polymer made up of ___
nucleotides
what makes cellulose different from starch
Cellulose forms long filaments, starch is branched
what monomers make up a protein
amino acids
triglyceride is a _____ made up of _____
lipid- glycerol, fatty acids
you can use starch or glycogen as an energy source but not cellulose because?
starch and cellulose have similar structure
what are differences between DNA and RNA
Deoxyribose (dna) vs. Ribose (rna)
Thyamine (dna) Uracil (rna)
double stranded helix(dna) vs single rna
a mutation in a single amino acid can alter which level of protein stucture
all
two different proteins have similar structure, we can infer_____
similar function
what makes triglycerides untstable in water
non polar c-h bonds in fatty acids
spontaneous formation of lipid bilayer in aqua environment is because
polar heads of phospholipids can interact with water (hydrophillic)
fatty acid tails are hydrophobic
