Modified Unit 2 Exam - Matter & Energy

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. It is essential for the survival of most organisms.

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

6 H2O + 6 CO2 + Light → C6H12O6 + 6 O2.

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem and transferring energy through cellular respiration.

Increased solar energy typically leads to an increase in phytoplankton populations due to enhanced photosynthesis.

The primary function of photosynthesis is to convert light energy into chemical energy, providing food and oxygen for other organisms.

Photosynthesis converts light energy into chemical energy (glucose), while cellular respiration converts glucose into usable energy (ATP) for cells.

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Oxygen is a key reactant in cellular respiration, allowing for the complete breakdown of glucose to produce ATP.

The products of cellular respiration are carbon dioxide, water, and ATP.
