Energy and Photosynthesis Review

Energy for the cell

What is ATP used for?

terminal phosphate group is broken off

What happens when ATP releases energy

autotroph

produces own food

plant photosynthesis

What is an example of an autotroph

heterotroph

must consume bc it cant produce its own food

human

what is an example of a heterotroph

pigment

chemical compound that gives color to a substance by absorbing light

chlorophyll

what is the main pigment in plants?

blue-violet and red light

What wavelengths of light are absorbed by chlorophyll?

sunlight

What do plants need to begin photosynthesis

outer membrane

what is A?

inner membrane

what is E?

stroma

what is B?

thylakoid

what is D?

granum

What is C?

reflects green light

What property does chlorophyll have that makes plants green?

6CO2+6H20 >C6 H12 06+602

Type the chemical formula equation for photosynthesis

carbon dioxide + water > glucose+ oxygen

Type the written formula for photosynthesis

NADP+

becomes NADPH with the addition of 2 high energy electrons

NADPH

high energy electron carrier and is used to help turn CO2 into glucose

oxygen

what is the gas PRODUCED by photosynthesis

thylakoid membrane

where does the light reaction happen?

ATP, NADPH, oxygen

what are the products of the light reaction

glucose

what is the product of the calvin cycle?

stroma

where does the calvin cycle take place?

mesophyll of leaves

where do most of the photosynthetic reactions take place in the plant?

stomata

openings or pores on the underside of a leaf where carbon dioxide enters and exits

if you increase light intensity, the photo rate will increase

what is the overall effect of light intensity on the rate of photosynthesis?
