Organisms that produce their own food

Autotrophs

1

Organisms that obtain energy from the food they eat

Heterotrophs

2

One of the principle chemical compounds that cells use to store and release energy

ATP (adenosine triphosphate)

3

Looks almost like ATP but has two phosphate instead of three

ADP

4

When a cell has energy available, it can store small amounts of it by adding a ________ to ADP which makes ATP

Phosphate

5

Energy is released by breaking the chemical bond between the:

second and third phosphate groups

6

Photosynthesis equation reactants are:

6 carbon dioxide molecules and 6 water molecules

7

Photosynthesis uses the energy of

Sunlight and enzymes

8

Photosynthesis products are:

Glucose and 6 oxygen molecules

9

In addition to water and carbon dioxide, photosynthesis requires:

Light, chloroplasts, and chlorophyll

10

Sunlight is a mixture of different _______

Wavelengths of light, all of which correspond to different colors

11

Pigments are light _____ molecules that gather the sun's energy

Absorbing

12

The primary pigment in plants

Chlorophyll

13

What absorbs light in the blue-violet and red regions, and reflects light in the green?

Chlorophyll

14

Where do light-dependent reactions take place?

Chloroplasts- thylakoid

15

Use energy from sunlight to produce oxygen and convert ADP and NADP+ into the energy carriers ATP and NADPH

Light-dependent reactions

16

Uses water, ADP, NADP+

Light-dependent reactions

17

Produces oxygen, ATP, NADPH

Light-dependent reactions

18

Where do light-independent reactions take place?

Chloroplasts- Stroma

19

Uses ATP and NADPH from light reactions to make high-energy sugars

23

Produces sugar, ADP, NADP+

Light-independent reactions

24

3 factors that affect photosynthesis:

-availability of water
-temperature
-intensity of light
