Study Notes
Key Concepts of Cell Energy Cycle
-
Aerobic Respiration
- A chemical process that utilizes oxygen to convert carbohydrates into energy.
- Produces 30 to 38 ATP molecules from one molecule of glucose.
-
Glucose
- A primary carbohydrate that is broken down during aerobic respiration to release energy.
-
Anaerobic Respiration
- A process where carbohydrates are partially degraded without oxygen.
- Generates significantly less energy than aerobic respiration.
-
ATP (Adenosine Triphosphate)
- The main energy currency of cells, powering cellular activities.
- Energy is released when ATP converts to ADP (Adenosine Diphosphate).
-
Cellular Respiration
- The method cells utilize to extract energy from food.
- Produces limited energy from glucose breakdown in the absence of oxygen.
-
By-products of Respiration
- Anaerobic respiration can yield by-products like lactic acid and alcohol.
- Aerobic respiration results in carbon dioxide and water as by-products.
Energy Types in Biological Processes
-
Chemical Energy
- Released or absorbed during chemical reactions, crucial for cellular functions.
-
Energy Storage
- Chemical energy is stored in glucose and ATP within cells.
-
Chlorophyll
- A green pigment found in chloroplasts that transforms light energy into usable chemical energy for plants.
-
Photosynthesis
- Occurs in chloroplasts, combining light energy with water and carbon dioxide to produce glucose and oxygen.
Cellular Structures and Processes
-
Cytoplasm
- A viscous fluid that fills a cell, mainly composed of water, situated between the cell membrane and nucleus.
-
Glycolysis
- The initial stage of glucose breakdown occurring in the cytoplasm, converting glucose into pyruvic acid without oxygen consumption.
-
Mitochondria
- Known as the powerhouse of eukaryotic cells, these organelles conduct aerobic respiration.
-
Radiant Energy
- Energy in the form of electromagnetic radiation, exemplified by light and heat, utilized in photosynthesis.
