A cell is the basic building block of life. It is the smallest unit that can carry out all the functions necessary for life.
A tissue is a group of cells that work together to perform a specific function. Tissues can be made up of similar or different types of cells.
An organ is a structure made up of different types of tissues that work together to perform a specific function. Examples include the heart, lungs, and liver.
An organ system is a group of organs that work together to accomplish a specific process in the body, such as digestion or circulation.
Digestion is a metabolic process that breaks down food into smaller molecules that can be used in chemical reactions to sustain life. It involves both mechanical and chemical processes.
Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. This process occurs until equilibrium is reached.
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. Catalysts can lower the activation energy required for reactions.
An enzyme is a type of protein that acts as a biological catalyst in living organisms. Enzymes speed up chemical reactions by lowering the activation energy needed.
Autotrophs are organisms that produce their own food through processes like photosynthesis or chemosynthesis. They convert inorganic substances into organic matter.
Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.
The rate of reaction refers to how much product is produced per unit of time in a chemical reaction. It can be influenced by factors such as temperature, concentration, and the presence of catalysts.
Respiration is the process by which all living organisms extract energy from their food. It involves the breakdown of glucose to release energy.
Aerobic respiration is a type of respiration that requires oxygen to produce energy. It is more efficient than anaerobic respiration and produces carbon dioxide and water as byproducts.
Anaerobic respiration is a type of respiration that occurs without oxygen. It produces less energy than aerobic respiration and can result in byproducts like lactic acid or ethanol.
ATP, or adenosine triphosphate, is a molecule that stores and releases energy for cellular processes. It is often referred to as the energy currency of the cell.
