The enzyme peptidase is responsible for breaking down protein molecules into
fatty acids
sugars
amino acids
nucleic acids
Which molecule has the incorrect function listed?
the lipids - they are responsible for long term energy
the proteins - they are responsible for for helping plants retain water
the carbohydrates - they are responsible for the structure of the cell membrane
the nucleic acids - they are responsible for supporting the immune system
Lipids and carbohydrates are dissimilar in that
carbs are made of water and ammonia, & lipids are made of only water
carbs of made of monomers and lipids are made of polymers
carbs are made of nucleotides and lipids are made of sugars
carbs are made of monosaccharides & lipids are made of fatty acids

0-4
4-5.5
5.5-8
10-12
Which statement is valid (true) based on the graph?
The optimum (best) temperature of the enzyme is 30 degrees
The optimum (best) temperature of the enzyme is 58 degrees
The enzyme is denatured (destroyed) at 45 degrees
The enzyme is denatured (destroyed) at 60 degrees
Enzyme and substrates fit together in a Lock-and-Key model. What does this mean?
substrates get reshaped by other enzymes to fit
enzymes can act upon all substrates they encounter
enzymes act upon substrates that it compliments but reshapes the ones that do not fit
enzymes only act upon the substrates that it compliments
