WITH EXPERT REVIEW
●● They give up electrons in order for NADH, ATP, NADPH, FADH2
to be created and take there electrons..
Answer: Explain the importance of water, oxygen, carbon dioxide, and
energy in terms of the general inputs and outputs of photosynthesis and
cellular respiration.
●● in the bonds.
Answer: Explain where energy is stored in a molecule of glucose.
●● the more the inner membrane has more surface area then they can
have more electron transport chains and atp synthase because the more
surface area the more atp can be produced..
Answer: Explain why the amplification of surface area is important to
the function of chloroplasts and mitochondria.
●● outer membrane- on the outside
inner membrane- just inside
thylakoid membrane- around the thylakoid
thylakoid lumen- individual thylakoid where hydrogen gradient is made
,stroma- space othr than the thylakoid/granum
light dependent cycle- thylakoid
calvin cycle- stroma
chlorophyll- photosystem 2
electron transport chain- between photosystem 1 and 2 in thylakoid
atp synthase molecules- from thylakoid to stroma..
Answer: Draw a chloroplast. Label the inner, outer, and thylakoid
membranes, the thylakoid lumen and the stroma. Identify the locations
of the light-dependent reactions, the Calvin cycle, chlorophyll
molecules, and the electron transport chain, and ATP synthase
molecules.
●● light dependent reaction- goes in: solar energy, h2o, adp, nadp+.
comes out: o2, atp, nadph
calvin cycle- goes in: atp, nadph, co2. comes out: nadp+, adp and a
carbohydrate glucose..
Answer: List the inputs and outputs of the light-dependent reactions and
of the Calvin cycle.
●● light dependent reaction.
Answer: Identify the pathway in photosynthesis in which light energy is
transformed and captured as chemical energy.
●● calvin cycle.
, Answer: Identify the pathway in photosynthesis in which chemical
energy is stored in a carbohydrate molecule.
●● photosytem- complex chlorophyll molecules and proteins that
harvest light energy. They are found in the thylakoid. They are important
because photosystem 2 takes in light energy and water and takes the
hydrogens and releases the oxygen which slightly excites the electrons
and then the electron is passed down the electron transport chain where
photosystem 1 gets the electron and excites it a lot where NADP+ grabs
the electron and is reduced to NADPH, ATP is also produced.
Answer: Explain what a photosystem is and where photosystems are
located, and why they are important to photosynthesis
●● H2O is split apart to two hydrogen atoms and an oxygen where the
oxygen is released and the hydrogen's become electrons which
eventually combine with CO2 to make the carbohydrate which is sugar..
Answer: Explain the importance of water molecules to the light-
dependent reactions.
●● in the water molecule that is split apart.
Answer: Explain where the oxygen gas comes from that is produced
during photosynthesis.
●● the energy released from the electron transport chain is used to move
hydrogen ions from the stroma into the thylakoid lumen. The large
number of hydrogen ions inside the lumen creates a gradient that allows
