What is the name of the structure labeled ‘4’

Stroma

What is the name of the structure labeled ‘5’

Thylakoid

What is the name of the structure labeled ‘6’

Lamella

What is a group of Thylakoids called?

Granum

What is the chemical equation for Photosynthesis?

6CO2 + 6H2O ( + Sunlight ) → C6H12O6 + 6O2

Where do ‘light’ reactions occur in the chloroplast?

within the thylakoid membrane

Where do ‘dark’ reactions occur in the chloroplast?

in the stroma

What is the purpose/function of the outer membrane of the chloroplast?

highly permeable to small molecules and ions, acting as the protective outer boundary of the chloroplast

What is the purpose/function of the inner membrane of the chloroplast?

regulates the passage of materials, including proteins and metabolites, into and out of the stroma. It often houses transport proteins and is a site for the synthesis of lipids and pigments

What is the purpose/function of the intermembrane space of the chloroplast?

It separates the two membranes, allowing them to maintain different compositions.

What is the purpose/function of the stroma of the chloroplast?

It is the site of the light-independent reactions, (Dark reactions, Calvin Cycle), where CO₂ is converted into sugar.

What is the purpose/function of the Thylakoids in the chloroplast?

Their primary role is to house the light-dependent reactions of photosynthesis. They also hold the pigment chlorophyll.

Where are the chlorophyll pigments located within the chloroplast?

Thylakoid

What is the purpose/function of the Grana in the chloroplast?

They allow efficient light harvesting and house the photosystems and electron transport chain components needed to generate ATP and NADPH.

What is the purpose/function of the Lamellae in the chloroplast?

They act as bridges, keeping the stacks of grana connected, spaced apart, and properly arranged

What is reduction (REDox)

gaining electrons

what is oxidation (redOX)

losing electrons

In photosynthesis, redox reactions ultimately transfer CO₂ to…?

Glucose

In photosynthesis, redox reactions ultimately transfer H₂O to…?

O2

what are the reactants in a light-dependent reaction?

light, water, and ADP

what are the products in a light-dependent reaction?

ATP, NADPH, and O2

what is the purpose of light dependent reactions>

to convert light energy to ATP and NADPH
