Cellular Energy

the ability to do work

• power
• strength
• force
• energy

anabolic pathway in which light energy from the Sun is converted to chemical energy for use by living things

• Photosynthesis
• Fermentation
• Glycolysis
• Cellular respiration

all of the chemical reactions in a cell

• photosynthesis
• metabolism
• respiration
• excretion

energy-storing molecule in cells, made of an adenosine molecule, a ribose sugar, and three phosphate groups

• DNA
• Glucose
• Lipid
• ATP

catabolic pathway in which organic molecules are broken down to release energy

• Glycolysis
• Cellular respiration
• Photosynthesis
• Fermentation

molecules that absorb specific wavelengths of light

• proteins
• pigments
• chemicals
• enzymes

metabolic process that requires oxygen

• photosynthesis
• anaerobic respiration
• aerobic respiration
• cellular respiration

in cellular respiration, a series of anaerobic chemical reactions in the cytoplasm that break down glucose into pyruvate

• Photosynthesis
• Krebs cycle
• Fermentation
• Glycolysis

anaerobic reactions in the cytoplasm that regenerate NAD+ for glycolysis and produce ATP; supplies energy for aerobic organisms when oxygen is low

• Photosynthesis
• Cellular respiration
• Fermentation
• Metabolism

metabolic process that does not require oxygen

• anaerobic respiration
• aerobic respiration
• cellular respiration
• photosynthesis
