Unit 3 Cell Energetics

Front

What is the role of ADP in cellular energy transfer?

Back

ADP (adenosine diphosphate) acts as a low-energy molecule that can be converted into ATP (adenosine triphosphate) when energy is added, similar to a battery that needs recharging.

Front

Which organelles are responsible for cellular respiration in both plants and animals?

Back

Mitochondria are the organelles responsible for cellular respiration in both plants and animals.

Front

What is photosynthesis and which organisms primarily perform it?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.

Front

Why do green plants appear green?

Back

Green plants appear green because chlorophyll, the pigment involved in photosynthesis, absorbs light in the blue and red wavelengths but reflects green light.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy (ATP) compared to anaerobic respiration, which occurs without oxygen and produces less energy.

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are the organelles in plant cells that carry out photosynthesis, converting light energy into chemical energy.

Front

What is the significance of glucose in cellular metabolism?

Back

Glucose is a primary energy source for cells and is used in cellular respiration to produce ATP.

Front

How does light intensity affect the rate of photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point, after which other factors may limit the rate.
