When energy changes form, some is ALWAYS converted into

Heat

Cold

What organic molecule does photosynthesis produce?

Glucose

Sucrose

What two ways do enzymes change reactions?

The binding causes enzymes to change shape

Enzymes bind to a molecule to stress the reaction to happen

Similarities between Osmosis/Diffusion/Dialysis

Substance moves from a higher to lower concentration

They all work to transport water from a higher to lower concentration

Longer wavelengths means

Lower energy

Higher energy

What organic molecule pick up H+ after hydrolysis

Amine

Glucose

Sucrose

Photosynthesis equation

CO2 + H2O (light) C6H12O6 + O2

C6H12O6 + O2 + CO2
