Chapter 4 Vocab Flashcards
Adenosine diphosphate (ADP)
Low-energy molecule that can be converted to ATP by the addition of a phosphate
Adenosine triphosphate (ATP)
High-energy molecule that contains, within its bonds, energy that cells can use
Chemosynthesis
Process by which ATP is synthesized by using chemicals as an energy scorce instead of light
Photosynthesis
A process that captures energy from sunlight to make sugars that store chemical energy
Chlorophyll
A pigment molecule in chloroplasts that absorbs some of the energy in visible light
Thylakoids
Membrane-bound structure within chloroplasts that contains chlorophyll and other light-absorbing pigments
Light-dependent reactions
Part of photosynthesis that absorbs energy from sunlight and transfers energy to the light-independent reactions
Light-independent reactions
Part of photosynthesis that uses energy absorbed during the light-dependent reactions to sythesize carbohydrates
Cellular respiration
Process of producing ATP by breaking down carbon-based molecules when oxygen is present
Aerobic
A process that requires oxygen to occur
Glycolysis
An anaerobic process which splits glucose into two three-carbon molecules and makes two molecules of ATP
Anaerobic
A process that does not require oxygen to occur
Krebs cycle
Produces molecules that carry energy to the second part of cellular respiration
Fermentation
Anaerobic process by which ATP is produced by glycolysis
Lactic acid
Product of fermentation in many types of cells, including human muscle cells
