Biology OST Review Quizizz #1 (Units 1-2)

What is the process that cells use to regulate their internal environment?

• Metabolism

• Homeostasis

• Photosynthesis

• Cell Division

What is homeostasis?

• The ability of an organism to maintain a stable internal environment despite changes in external conditions.

• The process by which organisms reproduce and pass on their genetic material.

• The ability of an organism to adapt to its environment over time.

• The mechanism by which organisms obtain energy from food.

What factors can affect enzyme activity?

• Temperature, pH, and substrate concentration

• Enzyme concentration, product concentration, and light intensity

• Pressure, humidity, and enzyme concentration

• Substrate shape, enzyme shape, and color of the solution

What temperature does the enzyme work best at?

• 25°C

• 30°C

• 35°C

• 40°C

What are enzymes?

• Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

• Enzymes are carbohydrates that provide energy to cells.

• Enzymes are lipids that store genetic information.

• Enzymes are minerals that help in muscle contraction.

What type of transport does not require chemical energy?

• Active transport

• Facilitated diffusion

• Passive transport

• Endocytosis

What is the role of organelles in a cell?

• Organelles are responsible for the cell's shape and structure.

• Organelles perform specific functions that are essential for the cell's survival and operation.

• Organelles are involved in the cell's communication with other cells.

• Organelles are only present in plant cells and not in animal cells.

How much energy is transferred between each trophic level?

• 5% of the energy is transferred between each trophic level.

• 10% of the energy is transferred between each trophic level.

• 15% of the energy is transferred between each trophic level.

• 20% of the energy is transferred between each trophic level.

What is the primary function of enzymes in biological systems?

• To increase the activation energy of biochemical reactions.

• To act as a source of energy for cells.

• To lower the activation energy of biochemical reactions.

• To transport molecules across cell membranes.

What is the difference between active transport and passive transport?

• Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

• Active transport occurs only in plant cells, while passive transport occurs in animal cells.

• Passive transport requires energy, while active transport does not.

• Active transport and passive transport are the same processes.
