Midterm Review - 1 (2024-2025)

Front

What is the optimum pH for amylase activity?

Back

The optimum pH for amylase activity is around 6.7 to 7.0, which is near neutral.

Front

What happens to amylase in the stomach?

Back

Amylase becomes inactive in the stomach due to the acidic pH, which is not suitable for its function.

Front

What is the primary function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA (mRNA).

Front

What is the consequence of ribosome destruction in a cell?

Back

If ribosomes are destroyed, the cell would be unable to synthesize proteins, leading to cell dysfunction.

Front

What is active transport in cellular biology?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, initiating ecological succession.

Front

What type of succession occurs after a forest fire?

Back

Secondary succession occurs after a disturbance like a forest fire, where the soil remains intact and allows for regrowth.

Front

What factors can increase oxygen production in aquatic plants?

Back

Increasing light intensity, such as moving a light source closer, can enhance photosynthesis and increase oxygen production in aquatic plants.

Front

What is the role of light in photosynthesis?

Back

Light provides the energy needed for photosynthesis, allowing plants to convert carbon dioxide and water into glucose and oxygen.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact.
