Photosynthesis Practice

An organism that obtains its energy from the foods it eats is a (an)

Heterotroph

During the ______________ of photosynthesis, energy from sunlight is

used to form ATP, NADPH, and oxygen.

Light dependent reaction

The Light-dependent reactions of photosynthesis take place in the ________

membranes of chloroplast

Thylakoid

The Stage of Photosynthesis that uses ATP and NADPH to form high-energy sugars is

the ___________

Calvin cycle

A plant or other organism that is able to make its own food is a(an)

Autotroph

_________________ is the overall process in which sunlight is used to convert carbon

dioxide and water into oxygen and high-energy sugars

Photosynthesis

The region of the chloroplast in which the Calvin Cycle Occurs is the 

Stroma

Molecules that absorbs light

Chlorophyll a, chlorphyll b, carotenoids

Produces oxygen gas and converts ADP to ATP

Light dependent reactions

Allows CO2 and O2 to move in and out of the plant

Stomata

The splitting of water molecules is essential for the photosynthetic production of

NADPH

In a reduction reaction,

Hydrogen atom are gained

What two energy carrying molecules are produced by the light reactions of

photosynthesis?

ATP and NADPH

The region outside the thylakoid membranes

Stroma

Process by which autotrophs use sunlight to make high-energy sugars

Photosynthesis

16 – light

17 – H2O

18 – CO2

Thylakoid

The Calvin cycle of photosynthesis take place in the

Stroma

Photosynthesis takes place in which organelle?

Chloroplast

Molecule found inside the thylakoid layer

Chlorophyll

What products of the light dependent reactions are used during the light

independent reactions

ATP and NADPH

What bi-product of photosynthesis is unimportant to the plant but quite

important to people?

Oxygen

The overall goal of photosynthesis is to produce what?

Glucose/G3P/carbohydrate

Excited electrons bounce down an electron transport chain resulting in the production

of this.

ATP

What input into the Calvin cycle is not a product of the light dependent reactions?

CO2

Light-dependent reactions require.

Light

The light independent reactions contain mostly this cycle

Which wavelength of visible light has the greatest energy content?

Violet

The oxygen produced during photosynthesis comes from:

The first phase of the Calvin cycle is:

CO2 fixation

The enzyme that catalyses the fixation of CO2 is called:

RuBP
