Unit 2 Test Review 2025

Front

What is a prokaryote?

Back

A prokaryote is a single-celled organism that lacks a nucleus and other membrane-bound organelles. Examples include bacteria and archaea.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, resulting in the production of energy and byproducts like lactic acid.

Front

What is the relationship between temperature and photosynthesis?

Back

Photosynthesis rates can increase with temperature, up to a certain point, as enzymes involved in the process become more active.

Front

What are the reactants in the process of photosynthesis?

Back

The reactants in photosynthesis are carbon dioxide (6CO2) and water (6H2O), which are converted into glucose (C6H12O6) and oxygen (6O2).

Front

How does the structure of mitochondria relate to its function?

Back

Mitochondria have a folded inner membrane (cristae) that increases surface area for energy production through cellular respiration.

Front

What is aerobic respiration?

Back

Aerobic respiration is a process that requires oxygen to produce energy, resulting in carbon dioxide and water as byproducts.

Front

What is the role of the nucleus in a cell?

Back

The nucleus contains the cell's genetic material (DNA) and controls cellular activities, including growth, metabolism, and reproduction.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy stored in glucose.

Front

What is the significance of cellular respiration?

Back

Cellular respiration is essential for converting biochemical energy from nutrients into ATP, which powers cellular processes.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP).
