Introduction
Preparing for the AP Biology exam requires a comprehensive understanding of the fundamental concepts covered in Unit 1. Quizlet, an online learning platform, offers a valuable tool for students to reinforce their knowledge and enhance their test-taking skills.
Biology: The Study of Life
- Define biology: The scientific study of living organisms and their interactions with each other and the environment.
- Characteristics of living organisms: Reproduction, growth and development, response to stimuli, regulation, homeostasis, and adaptation.
- Levels of biological organization: Atoms, molecules, cells, tissues, organs, organ systems, and organisms.
Chemical Basis of Life
- Elements essential for life: Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
- Organic molecules: Carbohydrates, lipids, proteins, and nucleic acids.
- Water: Essential for life, comprising around 60-70% of human body weight.
Cells: The Basic Units of Life
- Cell theory: All organisms are composed of one or more cells.
- Types of cells: Prokaryotic and eukaryotic; prokaryotes lack a nucleus, while eukaryotes have a nucleus and other membrane-bound organelles.
- Cell organelles: Nucleus, ribosomes, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes.
Cell Membranes
- Structure of a cell membrane: Phospholipid bilayer with embedded proteins.
- Functions of a cell membrane: Regulates the movement of molecules into and out of the cell.
- Diffusion and osmosis: Passive transport processes where molecules move across the membrane.
Bioenergetics
- Thermodynamics: Laws governing energy transfer.
- ATP (adenosine triphosphate): Universal energy currency of cells.
- Cellular respiration: Process by which cells break down glucose to produce ATP.
- Photosynthesis: Process by which plants use sunlight to synthesize glucose.
Enzymes
- Definition of an enzyme: Protein that catalyzes chemical reactions.
- Characteristics of enzymes: Highly specific, increase reaction rates, and are not consumed during the reaction.
- Factors affecting enzyme activity: Temperature, pH, and presence of inhibitors and activators.
Quizlet Features and Strategies
- Flashcard builder: Create digital flashcards with questions and answers.
- Spaced repetition: Selectively reviews flashcards based on difficulty and time since last review.
- Quiz modes: Test your knowledge through multiple-choice quizzes, matching games, and written answers.
