The H+ concentration gradient is used to 

• make NADPH

• split a water molecule

• generate ATP

• form water

NGSS.HS-LS1-5

Plants use the following reactants for the light reaction

• Water and CO2

• Water and NADPH

• Water and NADP+

• NADPH and ATP

The NADP+ is

• oxidized during the light reaction

• reduced during the light reaction

• oxidized during the Calvin cycle

• reduced during the Calvin cycle

Photosystems are made of

• chloroplasts

• chromosomes

• chlorophyll

• cytoplasm

What is FALSE about the calvin cycle

• uses the light reactions products

• produces a three carbon sugar (G3P)

• produces carbon dioxide

• produces NADP+

The enzyme that unzips the DNA to prepare for replication

• helicase

• replicase

• polymerase

• synthase

In what phase of the cell cycle does DNA replication take place?

• G1

• S

• G2

• M

The process of DNA replication is called semi conservative because it results in

• none of these

• Two DNA molecules.  One original molecule and one with two new strands

• two exact copies with new strands

• two identical molecules, each with 1 original strand and one new.
