Study Notes
Energy Acquisition and Utilization
- Living organisms obtain and utilize energy from their surroundings through various processes, such as photosynthesis and cellular respiration.
Photosynthesis
- Photosynthesis occurs in chloroplasts, organelles found in plant cells.
- It is the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds.
Circulatory System
- The primary function of the circulatory system in the human body is to transport oxygen and nutrients to cells and remove waste products.
Cellular Respiration
- Cellular respiration is the process by which cells break down glucose to release energy in the form of ATP (adenosine triphosphate).
- It involves three stages: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Respiratory System
- The primary function of the respiratory system in humans is to bring oxygen into the body and remove carbon dioxide through the process of breathing.
Excretory System
- The excretory system is responsible for removing waste products, including nitrogenous wastes, from the body.
- It includes the kidneys, liver, skin, and lungs, which work together to filter waste and excess substances from the blood.
