DAT Trivia

The cell membrane consists of which of the following molecules?

• phospholipids

• carbohydrates

• proteins

• nucleic acids

Answer explanation

The cell membrane is made out of a phospholipid bilayer. Which consist of two hydrophobic fatty acid chains linked to a phosphate-containing hydrophilic head group

What reaction produces heat?

•  endothermic

• buffer

•  hydrogen

• exothermic

Answer explanation

In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat

• Lysosomes

• Golgi apparatus

• Nucleus

• Smooth Reticulum

What are the four types of organic macromolecules?

• Carbs, proteins, lipids, and nucleic acids

• Proteins, RNA, DNA, and polymers 

• Saturated fats, unsaturated fats, trans fats, sugar

• Lipids, Drugs, Metabolites, Phosphate

Maltose is made from which sugars? 

• Glucose and fructose

• Fructose and fructose 

• Galactose and glucose

• Glucose and glucose

Which of the following is NOT a function of proteins in living organisms?

• Storage

• Transport

• Transcription

• Structure

Answer explanation

Transcription is NOT a function of proteins. Translation is. Transcription a process of creating RNA strands from DNA, through RNA polymerase. Translation is a process from creating protein from RNA.

Which of the following is a monosaccharide?

• sucrose

• lactose

• glucose

• starch

Answer explanation

A monosaccharide is a sugar that cannot be hydrolyzed or simplified into another sugar.

Ex. Glucose, Fructose, Galactose

A disaccharide are sugars that are a combination of two monosaccharides.

What is the primary structure of a protein?

• Quaternary Structure

• alpha helix and beta sheets

• tertiary structure

• amino acid sequence

Answer explanation

The primary structure of a protein is defined as the sequence of amino acids linked together to form a polypeptide chain. Each amino acid is linked to the next amino acid through peptide bonds created during the protein biosynthesis process
