Photosynthesis Overview: Photosynthesis And Cellular Respiration Worksheet Answers
Photosynthesis is a vital process that converts light energy into chemical energy, providing the basis for life on Earth. It is a complex biochemical process that occurs in plant cells, algae, and some bacteria, using sunlight, carbon dioxide, and water to produce glucose and oxygen.
Diagram of Photosynthesis
The process of photosynthesis can be divided into two main stages: the light-dependent reactions and the Calvin cycle (light-independent reactions). The light-dependent reactions take place in the thylakoid membranes of chloroplasts and use light energy to split water molecules, releasing oxygen and generating ATP and NADPH.
The Calvin cycle uses the ATP and NADPH generated in the light-dependent reactions to fix carbon dioxide into glucose.

Cellular Respiration Overview
Cellular respiration is a series of metabolic reactions that occur in the cells of living organisms to convert biochemical energy from nutrients into ATP, the energy currency of the cell. It is an essential process for all living organisms, providing the energy needed for cell growth, maintenance, and reproduction.
Diagram of Cellular Respiration
Cellular respiration can be divided into three main stages: glycolysis, the Krebs cycle (citric acid cycle), and oxidative phosphorylation. Glycolysis occurs in the cytoplasm and breaks down glucose into two pyruvate molecules, releasing energy in the form of ATP. The Krebs cycle takes place in the mitochondrial matrix and further breaks down pyruvate, releasing more ATP, NADH, and FADH2.
Oxidative phosphorylation occurs in the inner mitochondrial membrane and uses the NADH and FADH2 generated in the previous stages to generate ATP.
