What are enzymes and how are digestive enzymes used in your digestive system?
A. They are lipids that help make fats to then pass on to other cells that need them
B. They are proteins that would break down the food into smaller pieces
C. They are lipids that help make membranes to move food into and out of the cell
D. They are proteins used to make more proteins for the digestive system
Which of the following statement(s) is true?
A. We use oxygen and glucose during cellular respiration to make ATP (energy) for our body.
B. We release carbon dioxide as a product of cellular respiration and send it out the body where plants will use it for photosynthesis

Cilia are small hair like projections that surround some cells, what is the function of these tiny structures?
A. To control what comes in and out of the cell
B. To keep airways clear of bacteria, mucus and debris
C. To make proteins
D. To help cells reproduce
Which of the following explains how this affects the cilia?
A. The thick mucus just suffocates the cells and kills them off one by one
B. The thick mucus traps other cells, so they stick together making infections more likely
C. The thick mucus pulls the infection into the cells causing damage.
D. The mucus is so thick that the cilia can’t move and if it can’t move it can’t clear out bacteria and infections are more likely to occur
One of the most common mutations is a 3-base pair deletion on the CFTR gene. Which of the following best describes the effects of a mutation like this?
A. A 3 base deletion will cause a frameshift to occur which will alter the entire amino acid sequence after the mutation for the gene
B. A 3 base deletion will only cause 1 amino acid to be deleted, so the protein can still form, but it will be mutated slightly
C. A 3 base deletion will cause environmental factors to affect the person and then mitosis will not be able to occur properly.
D. A 3 base deletion will cause 3 amino acids to be changed which will affect the folding and shape of the protein
If Chloride ions use the CFTR Channel to move out of the cell from where there are more to where there are less, what is this an example of?
A. Facilitated Diffusion
B. Osmosis
C. Active Transport
D. Simple Diffusion
Which of the following best describes why the water follows the salt?
A. Solutions: Salt is dissolved in water, so they stay connected as they move through the membrane
B. Osmosis: If salt moves outside the cell, the cell will be sitting in a hypertonic solution, so to balance it out, the water will move out of the cell.
C. Osmosis: Water moves across the membrane at equal rates with the salt and osmosis is the diffusion of water.
D. None of the above.
If the CFTR channel isn’t working properly in your lungs, it will cause thick mucus to form outside the cell. Your body then will have respiratory infections, inflammation and possible lung damage. This causes your body to get out of balance and your lungs can’t work properly. What term do we use to describe our body maintaining balance?
A. Homeostasis
B. Metabolism
C. Active Transport
D. Negative Feedback Loop
During which 10 years did we see the greatest improvement in life expectancy for people with CF?
A. 1940-1950
B. 1970-1980
C. 1980-1990
D. 1990-2000
