Starting with subcellular components and organelles, they will learn how these tiny structures contribute to the overall function of a cell. The students will also get to know about the cell size and its impact on material exchange, the role of plasma membranes, and how they maintain the cell’s internal environment. Membrane permeability, transport mechanisms, and the compartmentalization of eukaryotic cells are also part of this exciting journey. |
10-13% |
| Unit 3: Cellular Energetics |
This unit revolves around cellular energetics, focusing on enzymes, the cellular powerhouses. The students will explore enzyme structure and catalysis, as well as the environmental factors affecting enzyme function. Cellular energy and the processes of photosynthesis and cellular respiration, which allow organisms to capture and use energy, will be thoroughly discussed. Lastly, they will explore the concept of fitness in relation to an organism’s molecular diversity. |
12-16% |
| Unit 4: Cell Communication and Cell Cycle |
This unit is all about cell communication and the cell cycle. The students will discover how cells communicate with each other, both nearby and over long distances. Signal transduction pathways and how they produce cellular responses will be explored in detail. They will also delve into the regulation of the cell cycle, examining checkpoints and what happens when the cycle is disrupted. Additionally, they will investigate feedback mechanisms that help maintain balance in the cellular world. |
10-15% |
| Unit 5: Heredity |
This unit focuses on the transmission of genetic information from one generation to the next. The students will unravel the processes of meiosis and its role in genetic diversity, Mendelian genetics, and the inheritance of genes and traits as described by Mendel’s laws. They will also explore non-Mendelian genetics, environmental effects on phenotype, chromosomal inheritance, and how these processes generate genetic variation in sexual reproduction. |
8-11% |
| Unit 6: Gene Expression and Regulation |
This unit revolves around gene expression and regulation. The students will start by knowing about the DNA and RNA structure, followed by the mechanisms of replication, transcription, and translation. We’ll explore how genes are expressed and regulated and the impact of mutations on genotype and phenotype. Genetic engineering techniques in DNA analysis and manipulation will also be part of this exciting journey. |
12-16% |
| Unit 7: Natural Selection |
In this unit, the students will explore the causes and effects of natural selection, how humans can influence diversity within populations, and the role of random occurrences in shaping genetic makeup. They will also delve into the evidence for evolution, the concept of common ancestry, and the ongoing process of evolution in all living organisms. |
13-20% |
| Unit 8: Ecology |
This unit is all about ecology, the study of how organisms interact with their environment. The students will examine responses to the environment, energy flow through ecosystems, population ecology, and the effects of population density on resource availability. Community ecology, biodiversity, disruptions to ecosystems, and the resilience of ecosystems to environmental changes will also be discussed. Lastly, they will explore the fascinating origins of life on Earth. |
10-15% |
The AP Biology Exam consists of two main sections:
Multiple Choice and Free Response. The Multiple Choice section has 60 questions and lasts 1.5 hours, while the Free Response section has six questions and also lasts for 1.5 hours.
Each section is worth 50% of the exam score. The Multiple Choice questions cover a variety of topics, and the Free Response questions include long and short questions that assess different aspects of biology knowledge and skills. The exam is scored on a scale of 1 to 5, with 5 being the highest score. Scoring three or higher is generally considered a good performance.
The AP Biology exam primarily supports majors and fields related to biology and the life sciences. It is designed to assess a student’s understanding of fundamental concepts in biology and their ability to think critically and apply that knowledge.
Some of the majors and fields that the AP Biology exam can support include:
1. Biochemistry: Biochemistry majors study the chemical processes that occur within living organisms, and a strong foundation in biology is essential.
2. Neuroscience: While neuroscience is a specialized field, a solid understanding of the biological basis of the brain and nervous system can be advantageous, and AP Biology provides a good foundation for this.
3. Agricultural Sciences: Those interested in agriculture and crop sciences can benefit from a strong biological foundation, as it’s relevant to plant biology and agriculture.
4. Biomedical Sciences: Students pursuing careers in research or healthcare may find the foundational knowledge in biology from the AP exam helpful.
5. Environmental Studies: This interdisciplinary major combines aspects of biology, ecology, and sustainability, making AP Biology knowledge valuable.
6. Microbiology: Understanding the fundamentals of life sciences is crucial for microbiology, which deals with the study of microorganisms.
7. Ecology and Conservation Biology: AP Biology covers principles related to ecosystems, population dynamics, and conservation, which are vital in these majors.
8. Molecular Biology and Genetics: These majors focus on the molecular and genetic processes in living organisms, and a good grasp of biology is essential.
9. Environmental Science: Understanding ecological principles and ecosystems is crucial in this field, and AP Biology covers many relevant topics.
10. Zoology and Botany: These majors focus on the study of animals and plants, respectively, and AP Biology provides a foundational understanding of these organisms.
