Question 1: chlorophyll

Answer:

principal pigment of plants and other photosynthetic organisms

Question 2: adenosine triphosphate (ATP)

Answer:

compound used by cells to store and release energy

Question 3: NADP+

Answer:

carrier molecule that transfers high-energy electrons from chlorophyll to other molecules

Question 4: ATP synthase

Answer:

cluster of proteins that span the cell membrane and allow hydrogen ions (H+) to pass through it

Question 5: autotroph

Answer:

organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer

Question 6: light-independent reactions

Answer:

set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugars; also called the Calvin cycle

Question 7: light-dependent reactions

Answer:

set of reactions in photosynthesis that use energy from light to produce ATP and NADPH

Question 8: electron transport chain

Answer:

series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions

Question 9: stroma

Answer:

fluid portion of the chloroplast; outside of the thylakoids

Question 10: thylakoid

Answer:

saclike photosynthetic membranes found in chloroplasts

Question 11: Calvin cycle

Answer:

light-independent reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such a as sugar

Question 12: pigment

Answer:

light-absorbing molecule used by plants to gather the sun's energy

Question 13: heterotroph

Answer:

organism that obtains food by consuming other living things; also called a consumer

Question 14: photosystem

Answer:

cluster of chlorophyll and proteins found in thylakoids

Question 15: photosynthesis

Answer:

process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into energy-rich carbohydrates such as sugars and starches
