energy

“capture”

A process done by

autotrophs only

Take sunlight energy and use it to convert low-energy
organic molecules into

high-energy organic molecules

CO2 coverts into

glucose (C6H12O6)

requires water (H2O) to

donate electrons

Oxygen (O2) is a

by-product

6CO2 + 6H2O uses sunlight to convert into

C6H12O6 + 6O2

Glucose can then be converted into other (larger) organic
compounds like

fructose, starch, cellulose, fatty acids, etc.

C6H12O6 (glucose) + 6O2(Oxygen) converts to

6H2O (water) + 6CO2(carbon dioxide) + 36ATP (energy)

How does sunlight energy capture occur?

-photosynthetic pigments in plants
-Chloroplasts

Sunlight is made up of a spectrum of

Wavelengths

How can we measure photosynthesis?

the release of oxygen

Sodium bicarbonate (NaHCO3) was added to the water in the experiment where we placed plant material under a funnel and placed an inverted test tube on top of the stem. This was done in order to boost the amount of....

Carbon dioxide

Some bubbles were formed (and then accumulated at the top of the inverted test tube) in lab 7 for photosynthesis. Was this gas produced during the light dependent (LD) or light independent (LI) reaction of photosynthesis?

Light dependent (LD)

What gas was seen at the top of the inverted test tubes?

oxygen

What is the source of this gas produced from the inverted test tubes in lab 7?

water

An end product of photosynthesis is glucose, a 6-carbon sugar. Where does the carbon come from that makes up this glucose molecule?

carbon dioxide

Name one photosynthetic pigment found in spinach leaves
