Which of the following should be used to calculate the amount of compound required to
make a solution? - answer Molecular Weight
Match the macromolecule to its example and associated functions - Carbohydrates -
answer Example: Cellulose
Functions: energy storage, receptors, structure of plant cell wall
Match the macromolecule to its example and associated functions - Lipids - answer
Example: Cholesterol
Functions: membrane structure, energy storage
Match the macromolecule to its example and associated functions - Nucleic Acids -
answerExample: RNA
Functions: information storage and transfer
Match the macromolecule to its example and associated functions - Proteins -
answerExample: Enzymes
Functions: structure, receptors, transports
A solvent is the dissolved matter in a solution - answerFalse
Carbon dioxide as a by-product benefits the brewing and baking industry in a process
called fermentation. When microorganisms (usually yeast) undergo fermentation, they
obtain their energy by: - answerAnaerobic Respiration
The enzyme maltase catalyzes the break down of maltose into glucose. A technician
added maltase to a solution of maltose to be incubated at 37°C for 20 minutes. Samples
were taken from the reaction tube every five minutes, and the glucose and maltose
concentrations were measured. No maltose was left in the reaction after 15 minutes.
Which of the following graphs represents the change in glucose and maltose
concentrations over time? - answerIt wont let me upload my own image unless I pay
and I am not about to do that but its the one where the Maltose is 0 towards the end and
Glucose curves up and keeps going
, The enzyme maltase catalyzes the break down of maltose into glucose. A technician
added maltase to a solution of maltose to be incubated at 37°C. Samples were taken
from the reaction tube every five minutes over the course of one hour, to measure the
glucose concentration. After an hour, the technician noticed the water bath failed to
reach 37°C (it only warmed to 25°C).
Which of the following is the most likely outcome of the reaction? - answerThe enzyme
activity would decrease, yielding the same level of glucose over a longer time period
How does DNA differ from one species to another? - answerThe number of genes and
non-coding regions
Match the type of DNA to its correct description -
Circular, long DNA containing several thousand genes - answerProkaryotic DNA
Match the type of DNA to its correct description -
Cytoplasmic, circular DNA containing only a few genes - answerPlasmid DNA
Match the type of DNA to its correct description -
Linear, long pieces of DNA with many thousands of genes, contained within a nucleus -
answerEukaryotic DNA
A structural gene's code is 5' TAC ATG CCC TTA ATC 3', what will the mRNA transcript
be? - answer3' AUG UAC GGG AAU UAG 5'
The three-dimensional structure of a protein is largely determined by the amino acid
sequence - answerTrue
A single base pair change in a gene's DNA sequence can affect the shape and function
of the protein it encodes - answerTrue
Match the protein structure to its level of structure - Primary - answerAmino acid chain
Match the protein structure to its level of structure - Secondary - answerAlpha Helix /
Pleated Sheet
Match the protein structure to its level of structure - Tertiary - answerProtein folds
Match the protein structure to its level of structure - Quaternary - answerFolded protein
joins with other units
Select the option that represents the correct order of assembly in the cell: -
answerAmino acid, polypeptide, protein
