An Informative Quiz On Basic Biochemistry

-ose is the classic suffix for a carbohydrate. starch is a polysaccharide made solely of glucose.

two of these (nucleotide and amino acids) are monomers, so that limits the answer choices. lipids are made of fatty acids and carbohydrates are made of monosaccharides.

Carbohydrates are the primary source of quick energy for the body, as they are rapidly broken down into glucose, which can be readily used by cells for energy production during high-intensity activities like a soccer match.

enzymes are typically named after the substrate on which they act, and they typically end in -ase.

a monosaccharide is a monomer; all the rest are polymers

the bonds between atoms in both saturated and unsaturated are covalent. hydrogen bonds occur between atoms of different molecules. both have single bonds, but only unsaturated fatty acids have DOUBLE bonds, thus providing more space in between hydrogen atoms so the lipid can move more. this is why unsaturated fats are liquid at room temperature.

although "induced fit" is the best model now, the enzyme and substrate fit together like puzzle pieces, or like a lock and key. the enzyme is the lock, while the substrate is the key.

this matches the example with the monomer. cellulASE is an enzyme, which is a protein. cellulOSE would be the carbohydrate.

if you don't recall the structure (amino acid), look at the elements: C, H, O, and N. that's protein.

enzymes reduce the amount of energy needed but there will always be some activation energy required.

Increasing the temperature typically increases the rate of enzyme-catalyzed reactions up to a certain point. This is because higher temperatures provide more kinetic energy to the reacting molecules, leading to more frequent collisions and a higher likelihood of successful interactions between the enzyme and substrate. However, it's important to note that excessively high temperatures can denature enzymes, leading to a decrease in reaction rate or complete loss of enzyme activity. Therefore, while increasing the temperature can enhance reaction rates, it should be done within a suitable temperature range for the specific enzyme being used.

Nucleic acids, such as DNA and RNA, contain phosphorus as a key component of their structure, specifically in the phosphate groups that link nucleotide units together. Phosphorus is not a typical component of lipids. Lipids primarily consist of carbon, hydrogen, and oxygen, with some lipids containing sulfur in addition to these elements. While nucleic acids contain phosphorus, lipids do not, making phosphorus a distinguishing feature of nucleic acids

don't let the organism stuff at the end confuse you - that's just specific information used as examples. lipids provide insulation for organisms, no matter what kind they are. they also store energy but are not the main source of energy (this is carbohydrates).
