(d) A drug is designed to bind to cholera toxin and prevent the toxin from crossing the intestinal cell membrane. Scientists mix the drug with cholera toxin and then add this mixture and GTP to a sample of intestinal cell membranes. Predict the rate of cAMP production in pmol per mg adenylyl cyclase per min if the drug binds to all of the toxin.
During meiosis, double-strand breaks occur in chromatids. The breaks are either repaired by the exchange of genetic material between homologous nonsister chromatids, which is the process known as crossing over (Figure 1A), or they are simply repaired without any crossing over (Figure 1B). Plant breeders developing new varieties of corn are interest...
strains II and III . Strain I is higher/different (in the average number of crossovers) compared with strains II and III . Total for part (b)
(c) Based on the data, describe the relationship between the average number of double- 1 point strand breaks and the average number of crossovers in the strains of corn analyzed in the experiment. • (In general) there is a direct correlation/positive relationship (between the number of double-strand breaks and the number of chromatid crossovers). (...
Fireflies emit light when the enzyme luciferase catalyzes a reaction in which its substrate, D-luciferin, reacts to form oxyluciferin and other products (Figure 1). In order to determine the optimal temperature for this enzyme, scientists added ATP to a solution containing D-luciferin, luciferase, and other substances needed for the reaction. They ...
The following models represent all the interacting species in two different communities with some of the same species and feeding relationships. These models assume that both communities have the same initial biomass. The models can be used to understand the effects of human activities on the communities. Figure 1. Models of two different communiti...
Researchers are studying the use of RNA vaccines to protect individuals against certain diseases. To develop the vaccines, particular cells are first removed from an individual. Then mRNAs coding for specific proteins from a pathogen are introduced into the cells. The altered cells are injected back into the individual, where the cells make the pr...
Jan 26, 2022 · The 2022 AP Biology exam will be split equally between two sections: multiple-choice and free-response questions. Each section is worth 50 percent of the exam score. You will have 1 hour, 30 minutes to answer 60 multiple-choice questions and 1 hour, 30 minutes to answer 6 free-response questions.

60 multiple-choice questions, each with four answer choices (A-D) 90 minutes long. Worth 50% of your score. You'll get a mix of both stand-alone questions and questions in sets, with four to five questions per set. Until 2020, the AP Bio test also included grid-in questions in its multiple-choice section, but these have since been removed.
