Front (Question)

Light travels in waves called..

Back (Answer)

Photons

#3
Front (Question)

Photons is a..

Back (Answer)

Small unit of energy

#4
Front (Question)

Protons with short wavelengths have..

Back (Answer)

HIGH energy (Bad for us) - Ex. UV rays, X-rays, Gramma rays

#5
Front (Question)

Protons with long wavelengths have..

Back (Answer)

LOW energy

#6
Front (Question)

Plants uses ___ energy for photosynthesis

Back (Answer)

Visible light energy (Medium light energy)

#7
Front (Question)

Chlorophyll pigment is found in..

Back (Answer)

plants, algae, protists and cyanobacteria

#8
Front (Question)

A pigment is..

Back (Answer)

A compound that absorbs some colour of light and reflects another colour

#9
Front (Question)

Chlorophyll absorbs ___ which begins the process of photosynthesis.

Back (Answer)

Absorbs PHOTONS

#10
Front (Question)

What is the most important pigment?

Back (Answer)

Chlorophyll A

#11
Front (Question)

What colours does Chlorophyll A reflects when absorbing blue and red light?

Back (Answer)

Green / yellow

#12
Front (Question)

What are the 2 other pigments in most plants?

Back (Answer)

Chlorophyll B and Beta-carotene

#13
Front (Question)

What is the function of Chlorophyll B and Beta-carotene?

Back (Answer)

Absorbs photon wavelengths and passes their energy to Chlorophyll A

#14
Front (Question)

Chlorophyll B absorbs lighter ___ and ___ light Beta-carotene absorbs ___ and ___ light

Back (Answer)

Chlorophyll B absorbs blue and orange light Beta-carotene absorbs blue and green light

#15
Front (Question)

During fall, the amount of chlorophyll in plants is reduced because of..

Back (Answer)

the decreased rate of Photosynthesis. During the fall, we are given longer nights and less day, due to this, plants receive less sunlight.

#16
Front (Question)

What are the 2 energy containing molecules formed during photosynthesis?

Back (Answer)

ATP and NADPH

#17
Front (Question)

What is ATP?

Back (Answer)

ATP is the principle energy supply molecule for cellular function of all cells

#18
Front (Question)

ATP is formed by an addition of..

Back (Answer)

ADP and Phosphate

#19
Front (Question)

What causes the formation of NADPH?

Back (Answer)

During photosynthesis, NADP accepts 1 Hydrogen ion and 2 e- to form NADPH

#20
Front (Question)

NADPH is an electron donor, thus it can become..

Back (Answer)

NADP

#21
Front (Question)

NADPH is involved in..

Back (Answer)

Energy transfer

#22
Front (Question)

Oxidation is an reaction when when an atom or molecule..

Back (Answer)

Loses electrons

#23
Front (Question)

Reduction is when an atom or molecule..

Back (Answer)

Gains electrons

#24
Front (Question)

Reduction of NADP

Back (Answer)

NADP + H = NADPH
