Bio 2 Lab: Photosynthesis Quiz

What is the chemical equation for photosynthesis?

Carbon dioxide + water + light energy → sugar + oxygen + water

What is not an input in the photosynthesis reaction?

Oxygen

What is not an output in the photosynthesis reaction?

Carbon Dioxide

What is an essential input for the light reaction?

Water

What is an output of the photosynthesis reaction?

Oxygen

Which is a product of the light reaction?

Oxygen

Sugar is produced in the Calvin Cycle by

combining hydrogen produced in the light

reactions with ______?

Carbon Dioxide

What is a product of the Calvin Cycle (also called

the dark reaction)?

Sugar

What is an essential input for the Calvin

Cycle (also called the dark reaction)?

Carbon Dioxide

As the amplitude (wave height) of light

increases, what happens to its intensity?

The intensity increases

What property of light determines its

intensity?

Amplitude

T/F: The wavelength of light determines its

color.

True

Which intensity of light should be the worst

for photosynthesis?

25uE

Which color of light should be the worst for

photosynthesis?

Green

What was the function of DCPIP in the

experiment?

Acts as an artificial electron acceptor, changing color

from dark blue to light blue as photosynthesis takes

place

In the photosynthesis experiment, DCPIP

was used in place of what component of

the photosynthetic reaction?

NADPH

In the photosynthesis lab, you used a

spectrophotometer to measure?

The absorbance of oxidized DCPIP

In the photosynthesis lab, why was it

important to set the wavelength on your

spectrophotometer

To measure the absorbance of the sample at the

wavelength that is maximally absorbed by oxidized

DCPIP

Which cuvette could not be exposed to

light?

The control cuvette

What is the purpose of the blank

cuvette?

Contains everything in the experimental solution except

the DCPIP in order to calibrate the spectrophotometer
