- Metabolic Pathway:
- A series of enzyme-catalyzed reactions linked within a cell.
- Can be linear (e.g., glycolysis) or cyclical (e.g., Krebs and Calvin cycles).
- Key components:
- Initial reactant (e.g., A), intermediates (e.g., B and C), and the final product (e.g., D).
- Initial reactant (e.g., A), intermediates (e.g., B and C), and the final product (e.g., D).
- Autotrophs:
- Organisms that produce their own food.
- Photoautotrophs: Use light energy for photosynthesis (e.g., plants, cyanobacteria).
- Chemoautotrophs: Use inorganic substances (e.g., iron, sulfur) through chemosynthesis (e.g., certain bacteria, archaea).
- Heterotrophs:
- Obtain energy and matter by consuming or decomposing organic compounds produced by other organisms.
- Examples: Consumers, decomposers, parasites.
- Exergonic vs. Endergonic Reactions:
- Exergonic Reactions:
- Release energy and increase entropy.
- Examples: Cellular respiration, hydrolysis.
- Endergonic Reactions:
- Require energy and decrease entropy.
- Examples: Photosynthesis, dehydration synthesis.
- Exergonic Reactions:
- Structure and Function of ATP:
- Structure:
- Five-carbon sugar (ribose), nitrogenous base (adenine), and three phosphate groups.
- Function:
- Powers cellular work by storing and releasing energy.
- Energy storage: ADP + phosphate group → ATP (uses energy from food or light).
- Energy release: ATP → ADP + phosphate (releases energy for cellular processes).
- Structure:
- Energy Coupling:
- Links exergonic and endergonic reactions to drive biological processes.
- Examples:
- Cellular respiration (exergonic) drives ATP formation (endergonic).
- ATP breakdown drives active transport and muscle contraction (both endergonic processes).

[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” dataset_id=”AP_Bio_Flashcards_2022|1caae521aa910″ question_number=”108″ topic=”3.4.Cell_Energy”] What is the difference between linear and cyclical metabolic pathways?
[a] Linear metabolic pathways have a clear starting reactant and an ending product (e.g., glycolysis). Cyclical metabolic pathways, such as the Krebs cycle and Calvin cycle, regenerate their starting compound (e.g., oxaloacetate in the Krebs cycle) at the end of the pathway.
[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” dataset_id=”AP_Bio_Flashcards_2022|1cbbe8f19d910″ question_number=”109″ topic=”3.4.Cell_Energy”] What are the key differences between autotrophs and heterotrophs?
[a] Autotrophs produce their own food, either through photosynthesis (photoautotrophs) or chemosynthesis (chemoautotrophs). Heterotrophs obtain energy and matter by consuming organic compounds made by other organisms.
[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” dataset_id=”AP_Bio_Flashcards_2022|1cb5e7a41e910″ question_number=”111″ topic=”3.4.Cell_Energy”] Why is ATP known as the energy currency of the cell?
[a] ATP stores energy in its phosphate bonds and releases it when the terminal phosphate group is removed. This energy is used to power various cellular processes, making it the primary molecule for energy transfer in cells.
[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” dataset_id=”AP_Bio_Flashcards_2022|1cabe7f91c910″ question_number=”112″ topic=”3.4.Cell_Energy”] What is energy coupling?
[a] Energy coupling allows cells to use the energy released from exergonic reactions (e.g., breakdown of ATP) to drive endergonic reactions (e.g., active transport, muscle contraction).
[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” dataset_id=”AP_Bio_Flashcards_2022|1cb6d7e11e910″ question_number=”113″ topic=”3.4.Cell_Energy”] How do photoautotrophs and chemoautotrophs capture energy differently?
[a] Photoautotrophs capture energy from sunlight to perform photosynthesis, producing glucose and oxygen. Chemoautotrophs capture energy from oxidizing inorganic substances (e.g., iron, sulfur) to perform chemosynthesis, creating organic compounds.
[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” dataset_id=”AP_Bio_Flashcards_2022|1cab67a51d910″ question_number=”114″ topic=”3.4.Cell_Energy”] How do heterotrophs metabolize energy from organic compounds?
[a] Heterotrophs metabolize energy by breaking down carbohydrates, lipids, and proteins through processes like glycolysis, the Krebs cycle, and the electron transport chain. These processes release energy stored in chemical bonds to produce ATP.
[q json=”true” unit=”3.Cellular_Energetics” topic=”3.4.Cell_Energy” dataset_id=”AP_Bio_Flashcards_2022|1147a361ed84c6″ question_number=”99″] What is a metabolic pathway?
[a] A metabolic pathway is a linked series of enzyme-catalyzed chemical reactions occurring within a cell. The reactants, products, and intermediates of an enzymatic reaction are known as metabolites.
[q json=”true” unit=”3.Cellular_Energetics” topic=”3.4.Cell_Energy” dataset_id=”AP_Bio_Flashcards_2022|1146954c8a34c6″ question_number=”100″] What are autotrophs? Compare and contrast photoautotrophic and chemoautotrophic organisms.
[a] Autotrophs are organisms that can produce their own food. Photoautotrophs use the energy in light to create the organic compounds they need to survive through photosynthesis. Chemoautotrophs derive the energy for their life processes by chemosynthesis: oxidizing inorganic substances, including iron, sulfur, or hydrogen sulfide.
[q json=”true” unit=”3.Cellular_Energetics” topic=”3.4.Cell_Energy” dataset_id=”AP_Bio_Flashcards_2022|114568f28c50c6″ question_number=”101″] What are heterotrophs, and how do they get the energy and matter they need to live, grow, and reproduce?
[a] Heterotrophs are organisms that capture the energy present in organic compounds produced by other organisms. Heterotrophs can be ecological consumers, decomposers, or parasites. They get their energy and matter by metabolizing the organic compounds in organisms that they eat or absorb, or in the dead remains of organisms.
[q json=”true” unit=”3.Cellular_Energetics” topic=”3.4.Cell_Energy” dataset_id=”AP_Bio_Flashcards_2022|29a9feeeb83fa” question_number=”102″] What’s the difference between an exergonic reaction and an endergonic reaction.
[a] Exergonic reactions (1) release energy and increase entropy. Examples include cellular respiration and most hydrolysis reactions. Endergonic reactions (2) require energy and decrease entropy. Examples include photosynthesis or almost any dehydration synthesis reaction.
[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” topic=”3.4.Cell_Energy” dataset_id=”AP_Bio_Flashcards_2022|219576c998c64c” question_number=”105″] Describe the structure and function of ATP.
[a] ATP consists of the 5-carbon sugar ribose (1), the nitrogenous base adenine (2), and 3 phosphate groups (3). ATP is used to power work within cells. Every cell makes its own ATP, and there’s no sharing of ATP between cells.
[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” topic=”3.4.Cell_Energy” dataset_id=”AP_Bio_Flashcards_2022|219494f117624c” question_number=”106″] Describe how ATP can be used to store and release energy.
[a] For temporary storage of energy, cells take energy from food (during cellular respiration) or light (during photosynthesis) and use it to make ATP from ADP and Pi. To release energy to perform cellular work, cells remove a phosphate group from ATP, creating ADP and Pi.
[q json=”true” yy=”4″ unit=”3.Cellular_Energetics” topic=”3.4.Cell_Energy” dataset_id=”AP_Bio_Flashcards_2022|15ab151b97a7a1″ question_number=”107″] What is energy coupling?
[a] Energy coupling involves linking an exergonic reaction to an endergonic one (which provides the energy to drive the endergonic reaction forward). For example, cellular respiration (which is exergonic) drives the formation of ATP from ADP and Pi (which is endergonic). The exergonic conversion of ATP and ADP and Pi is coupled to endergonic processes such as muscle contraction or dehydration synthesis reactions.
