Biology Semester 1 Final

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically moving from an area of high concentration to an area of low concentration.

Front

What is active transport?

Back

Active transport is the movement of substances across a cell membrane using energy, typically moving from an area of low concentration to an area of high concentration.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases, primarily carbon dioxide, in the atmosphere.

Front

What are proteins?

Back

Proteins are biomolecules made of amino acids that perform various functions in the body, including acting as enzymes and providing structural support.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6 CO₂ + 6 H₂O ------> C₆H₁₂O₆ + 6 O₂.

Front

What are carbohydrates?

Back

Carbohydrates are biomolecules that include sugars and starches, providing quick energy and structural support in cells.

Front

What role do enzymes play in biological processes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body without being consumed in the process.

Front

What is the function of lipids?

Back

Lipids are biomolecules that store energy, provide insulation, and make up cell membranes.

Front

What are nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are biomolecules that store and transmit genetic information.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration.
