- Q2All of the following are functions of proteins EXCEPT:store and transmit hereditybuild tissues such as bone and musclecontrol the rate of reactions and regulate cell processeshelp to fight disease120s
- Q3What are subunits of DNA and their function?lipids that store energy and provide insulationnucleotide that store informationmonosaccharide that provide quick energy for the cellproteins that provide building blocks for the structural components120s
- Q4Enzymes influence chemical reactions in living systems byaffecting the rate at which reactions occurproviding the substrate required for the reaction to occurcombining with excess hydrogen to form gaseous wastesabsorbing water released when polymers are formed120s
- Q5Many enzymes in the human body function best at 37°C. What is the most likely result of a significant increase in body temperature?Enzymes become more sluggish.Enzymes become denatured.Enzymes become hormones.Enzymes become more active.120s
- Q6How are the functions of a carbohydrate and a lipid similar?Both store genetic informationBoth dissolve nutrients in the digestive system.Both lower the activation energy of reactions.Both are a source of energy.120s
- Q7A biochemist is attempting to replicate a chemical reaction that commonly takes place in cells. During the chemical reaction, starch is broken down into glucose. What will most likely happen if the biochemist adds an enzyme to the reactants?The reaction will stopThe reaction will no longer take placeThe reaction will speed upThe reaction will slow down120s
