Semester 1 Final Review

Front

What happens to a red blood cell placed in pure water?

Back

It will swell and may burst due to osmosis, as water moves into the cell.

Front

How are diseases spread?

Back

Diseases can be spread through coughing, sneezing, contaminated water, and other means.

Front

What is diffusion?

Back

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

Front

What follows glycolysis when there is no oxygen present?

Back

Fermentation follows glycolysis in the absence of oxygen.

Front

How are cellular respiration and photosynthesis related?

Back

Photosynthesis removes carbon dioxide from the atmosphere, while cellular respiration releases it.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the role of enzymes in biological reactions?

Back

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

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

Front

What is the function of the mitochondria?

Back

Mitochondria are the powerhouse of the cell, where cellular respiration occurs to produce ATP.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.
