AP Biology FRQ 2022 Quiz

What is the primary focus of the 2022 AP Biology FRQ question discussed in the video?

• Photosynthesis processes

• G protein-coupled receptors

• DNA replication

• Cell division

What happens when an extracellular ligand binds to a G protein-coupled receptor?

• Chloride ions are absorbed

• GTP replaces GDP on the G protein

• ATP is converted to ADP

• Protein synthesis is halted

What is the role of cyclic AMP in the signaling pathway?

• It inhibits protein kinases

• It deactivates adenylate cyclase

• It activates protein kinases

• It binds to DNA

What effect does the CH toxin have on intestinal cells?

• Promotes cell division

• Increases nutrient absorption

• Causes excessive water retention

• Leads to dehydration through diarrhea

In the experiment, which sample serves as the negative control?

• Sample 1

• Sample 2

• Sample 3

• Sample 4

What is the independent variable in the experiment?

• Rate of cyclic AMP production

• Presence of GTP and CH toxin

• Amount of water loss

• Number of intestinal cells

How does the presence of CH toxin affect cyclic AMP production?

• Decreases production

• Has no effect

• Increases production significantly

• Stops production completely

What is the predicted effect of a drug that binds to CH toxin?

• Decreases cyclic AMP production

• Has no effect on cyclic AMP production

• Increases cyclic AMP production

• Prevents cyclic AMP production

What is the expected outcome if a mutant adenylate cyclase cannot be activated by the G subunit?

• Increased water loss

• Decreased chloride ion secretion

• No change in cyclic AMP production

• Increased nutrient absorption

Why is it important to understand experimental controls and variables in AP Biology?

• To memorize all biological terms

• To synthesize information across chapters

• To avoid studying other subjects

• To perform better in lab reports
