Answers and Explanations
This section provides detailed answers and explanations for each Free Response Question (FRQ) in the 2016 AP Biology exam. The answers are organized using HTML blockquotes for clarity.
FRQ 1
Question: Describe the structure and function of the cell membrane.
Structure:The cell membrane is a phospholipid bilayer, which means it is composed of two layers of phospholipids. Each phospholipid molecule has a hydrophilic (water-loving) head and a hydrophobic (water-hating) tail. The hydrophilic heads face outward, interacting with the aqueous environment inside and outside the cell.
The hydrophobic tails face inward, interacting with each other and forming a barrier to the passage of water-soluble molecules.
Function:The cell membrane serves several important functions, including:
- Barrier function:The cell membrane acts as a barrier, preventing the entry of harmful substances into the cell and the leakage of essential substances out of the cell.
- Transport function:The cell membrane regulates the transport of substances into and out of the cell. This is accomplished through a variety of mechanisms, including passive diffusion, facilitated diffusion, and active transport.
- Signal transduction function:The cell membrane contains receptors that bind to specific molecules, such as hormones and neurotransmitters. This binding triggers a cascade of events that results in a change in cell activity.
- Cell recognition function:The cell membrane contains glycoproteins and glycolipids that are unique to each cell type. These molecules allow cells to recognize each other and interact with each other.
FRQ 2
Question: Explain how the structure of the respiratory system is related to its function.
The respiratory system is composed of a series of structures that work together to facilitate the exchange of gases between the blood and the environment. The main structures of the respiratory system include the nose, pharynx, larynx, trachea, bronchi, and lungs.
The structure of the respiratory system is closely related to its function. For example, the nose and pharynx are lined with mucus-producing cells that help to trap dust and other particles from entering the lungs. The larynx contains vocal cords that vibrate to produce sound. The trachea is a long, thin tube that carries air to and from the lungs. The bronchi are the branches of the trachea that lead to the lungs. The lungs are composed of millions of tiny air sacs called alveoli. The alveoli are lined with capillaries, which are small blood vessels that allow for the exchange of gases between the blood and the air.
The structure of the respiratory system allows for the efficient exchange of gases between the blood and the environment. The large surface area of the alveoli provides a large area for gas exchange. The thin walls of the alveoli and capillaries allow for the rapid diffusion of gases between the blood and the air.
FRQ 3
Question: Describe the role of DNA in protein synthesis.
DNA is the genetic material of all living organisms. It contains the instructions for making all of the proteins that are necessary for life.
The process of protein synthesis involves two main steps: transcription and translation.
- Transcription:During transcription, the DNA sequence of a gene is copied into a molecule of messenger RNA (mRNA). The mRNA molecule then travels out of the nucleus and into the cytoplasm.
- Translation:During translation, the mRNA molecule is read by a ribosome. The ribosome translates the mRNA sequence into a sequence of amino acids, which are then linked together to form a protein.
DNA plays a critical role in protein synthesis by providing the instructions for making proteins. The sequence of nucleotides in DNA determines the sequence of amino acids in a protein.

Key Concepts and Skills Tested
The 2016 AP Biology FRQs assessed a wide range of key concepts and skills, covering all four Big Ideas and multiple science practices. These questions required students to demonstrate their understanding of fundamental biological principles, their ability to analyze and interpret data, and their proficiency in applying scientific reasoning and problem-solving skills.
Concepts and Skills Tested
The following table summarizes the key concepts and skills tested in each FRQ:
| Concept/Skill | Question Number | Explanation |
|---|---|---|
| Cell Structure and Function | 1 | Students had to identify the structures of a plant cell and explain their functions. |
| Meiosis | 2 | Students had to describe the process of meiosis and explain how it contributes to genetic variation. |
| Evolution | 3 | Students had to analyze data on the evolution of antibiotic resistance in bacteria and explain the mechanisms of natural selection. |
| Gene Expression | 4 | Students had to describe the process of gene expression and explain how mutations can affect protein structure and function. |
| Plant Physiology | 5 | Students had to design an experiment to investigate the effects of light intensity on plant growth. |
| Animal Behavior | 6 | Students had to analyze data on the behavior of ants and explain the role of pheromones in communication. |
| Ecology | 7 | Students had to analyze data on the population dynamics of a predator-prey system and explain the factors that affect population growth and decline. |
| Scientific Reasoning | All | All FRQs required students to demonstrate their ability to reason scientifically, analyze data, and draw conclusions based on evidence. |
Common Mistakes and Misconceptions
Students frequently make mistakes and hold misconceptions on the AP Biology FRQs. These errors can result in lost points and a lower overall score. Here are some typical errors and misconceptions to be aware of:
Not understanding the question
- Students frequently misread the question or fail to fully grasp what is being asked. This can lead to irrelevant or incomplete responses.
- For instance, in the 2016 FRQ on plant growth, some students discussed the role of light in photosynthesis rather than focusing on the question about the impact of auxin on root growth.
Lack of specific evidence, Ap bio frq 2016 answers
- Students sometimes fail to provide specific evidence to support their claims. They may make general statements or use vague language.
- In the FRQ on gene regulation, some students stated that “transcription factors regulate gene expression” without providing specific examples or explaining the mechanism involved.
Incorrect application of concepts
- Students may apply concepts incorrectly or in an oversimplified manner. This can lead to incorrect conclusions or flawed reasoning.
- In the FRQ on evolution, some students incorrectly assumed that natural selection always leads to increased fitness, ignoring the role of environmental factors and genetic variation.
Mixing up concepts
- Students may confuse or mix up different concepts, leading to incorrect answers.
- In the FRQ on cell signaling, some students incorrectly described G proteins as receptors, confusing their roles in signal transduction.
Study Strategies and Tips: Ap Bio Frq 2016 Answers
Preparing for the AP Biology FRQs requires a comprehensive approach that combines effective content review, question-answering practice, and time management strategies. Here are some proven tips to help you excel in the exam:
Content Review
* Create a structured study plan that allocates sufficient time for reviewing all essential concepts.
- Utilize textbooks, lecture notes, and online resources to gain a thorough understanding of the material.
