TEAS 7-Biology questions and answers 2024\2025
GradeA+
Monomers
- correct answer small molecular building blocks of polymers
Endothermic Reaction
- correct answer A reaction that ABSORBS energy in the form of heat
Hydrolysis
- correct answer a chemical reaction that adds water to a macromolecule in order to break its covalent
bond; key component in digestion
The creation of macromolecules is what kind of reaction?
- correct answer Endothermic reaction called dehydration
The breakdown of macromolecules is what kind of reaction?
- correct answer Exothermic reaction called hydrolysis
4 Types of Macromolecules
- correct answer carbohydrates, lipids, proteins, nucleic acids
Macromolecules are also known as
- correct answer biopolymers
Simplest unit of a carbohydrate
- correct answer monosaccharide
, At the molecular level, carbohydrates contain
- correct answer Carbon, hydrogen, and oxygen
Glucose
- correct answer A very common carbohydrate monomer that exists as a hexose (meaning it has 6
carbons in it).
Carbohydrate monomers tend to end in
- correct answer -ose
Carbohydrate functions in living systems
- correct answer 1. storage
2. structure
3. communication/recognition
Plants use carbohydrates in the form of
- correct answer cellulose
chitin
- correct answer carbohydrate used by fungi to add structure to their cell wall and by
insects/anthropods in their exoskeleton
Glycoprotein
- correct answer A protein with one or more carbohydrates covalently attached to it, used by the human
body for cellular recognition. Oligosaccharide with amino acids attached that attaches to a cell's lipid
membrane in cellular recognition; antibody, immunoglobulin
Carbohydrate stored in the liver
- correct answer glycogen
Smallest unit of a lipid
- correct answer fatty acid
