#1
Front (Question)

There are two sets of reactions..

Back (Answer)

Light dependant reaction Light indépendant reaction

#2
Front (Question)

Light dependant reaction requires

Back (Answer)

Light energy and Water

#3
Front (Question)

Light dependant reaction products

Back (Answer)

ATP, NADPH, Oxygen

#4
Front (Question)

Light Independent reaction requires

Back (Answer)

ATP, CO2, NADPH, RuBP

#5
Front (Question)

Light independent reaction products

Back (Answer)

PGAL (Also known as G3P)

#6
Front (Question)

In light dependant reactions, what is trapped and used to generate 2 high-energy compounds ____ & ____

Back (Answer)

Traps solar energy and produces ATP and NADPH

#7
Front (Question)

In light dependant reactions, the energy of ATP and the reducing power of NADPH are used to..

Back (Answer)

Reduce carbon dioxide and make glucose

#8
Front (Question)

The main purpose of the light dependant reaction is to..

Back (Answer)

Synthesize ATP and NADPH in the Stroma

#9
Front (Question)

The synthesization of ATP and NADPH in the Stroma releases..

Back (Answer)

Oxygen

#10
Front (Question)

Light energy splits..

Back (Answer)

Water molecule in the Thylakoid during the process of photosynthesis

#11
Front (Question)

The first process of light dependent reaction..

Back (Answer)

Light energy splits water in thylakoid

#12
Front (Question)

The second process of light dependent reaction..

Back (Answer)

PSI II accepts an electron from the water. Solar energy strikes the PSI II and the electron causing it to be “excited”.

#13
Front (Question)

The third process of light dependent reaction..

Back (Answer)

The electron reaches the electron accepter of PSI II and is passed down

#14
Front (Question)

The electron gets passed down a series of other molecules embedded in the thylakoid membrane known as..

Back (Answer)

Electron transport change

#15
Front (Question)

The forth process of light dependent reaction..

Back (Answer)

A small amount of energy is released and this pushes H from the Stroma, across the Thylakoid membrane and into the Thylakoid space

#16
Front (Question)

The fifth process of light dependent reaction..

Back (Answer)

H ion concentration becomes higher in the thylakoid creating a concentration gradient

#17
Front (Question)

The sixth process of light dependent reaction..

Back (Answer)

Light is absorbed by Photosystem I where the electron becomes excited and is passed to an electron acceptor

#18
Front (Question)

The seventh process of light dependent reaction..

Back (Answer)

The election is combined with NADP to form NADPH with the help of NADP reductase (enzyme)

#19
Front (Question)

When Hydrogen ions are forced from the Stroma to the Thylakoid space, they can’t diffuse back because..

Back (Answer)

The membrane is impermeable (not allowing fluid to pass) to these ions

#20
Front (Question)

ATP synthase allow..

Back (Answer)

Allows hydrogen ions to move down their gradient and try to reach the equilibrium

#21
Front (Question)

The energy is used to convert ADP + P –> ATP in a process called..

Back (Answer)

Chemiosmosis
