NGSS.HS-LS2-3

During this process, ATP and NADPH are spent/oxidized

Which statement is true of the light dependent reactions?

• It occurs in the stroma

• It occurs in the thlyakoids

• It results in the production of CO2

• It is an unwanted byproduct of evolving before oxygen existed

Which process we learned produces the most NADH?

True or false: Animal cells use mitochondria to produce ATP whereas plants use chloroplasts to produce ATP and therefore don't need mitochondria

• true

• false
