Study Notes
Biological Processes
- ATP Generation: The process of breaking down organic molecules to produce adenosine triphosphate (ATP) is known as cellular respiration. This process involves glycolysis, the Krebs cycle, and oxidative phosphorylation.
- Photosynthesis: Plants that synthesize their own organic molecules from carbon dioxide (CO2) and inorganic materials are called autotrophs.
Waste Products and Energy Conversion
- Respiration Waste Products: Carbon dioxide (CO2) and water (H2O) are the primary waste products of cellular respiration.
- Light Energy Conversion: Chloroplasts convert light energy into chemical energy through photosynthesis, primarily involving the light-dependent and light-independent reactions.
Levels of Biological Organization
- Ecosystem Summit: The biosphere is defined as the sum of all ecosystems on Earth, showcasing the interactions between living organisms and their environments.
Properties of Water and Life
- Polar Nature of Water: Water molecules are polar due to the unequal sharing of electrons between hydrogen and oxygen atoms, resulting in a partial positive charge on hydrogen and a partial negative charge on oxygen.
- Non-Life Property: A lack of reproductive capability is NOT considered a property of life.
Functions of Living Organisms
- Regulation: The primary function of regulation in living organisms is maintaining homeostasis, ensuring stable internal conditions.
- Evolutionary Adaptation: Evolutionary adaptation is best described as the process by which populations become better suited to their environments over generations.
- Energy Processing: The primary role of energy processing in living organisms is to convert energy from food or sunlight into usable forms for cellular activities.
- Order in Living Organisms: Order refers to the organized structure of living organisms, which is essential for maintaining life.
- Growth and Development: The primary function of growth and development in living organisms is to facilitate the changes that occur from conception to maturity, allowing for complexity and organization.
