PHOTOSYNTHESIS

Question 1

Plants are called ___________ because they can use energy from light to synthesize, or make, their own food source.

Answer 1

autotrophs

Question 2

plants use sunlight, water, and the gases in the air to make _______, which is a form of sugar that plants need to survive.

Answer 2

glucose

Question 3

To perform photosynthesis, plants need three things: ____________________.

Answer 3

carbon dioxide, water, and sunlight

Question 4

Animals take in gases through a process called ________.

Answer 4

respiration

Question 5

During the respiration process, animals inhale all of the gases in the atmosphere, but the only gas that is retained and not immediately exhaled is _______.

Answer 5

oxygen

Question 6

formula for photosynthesis

Answer 6

6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2

Question 7

the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.

Answer 7

Chlorophyll

Question 8

where does photosynthesis takes place in plants

Answer 8

chloroplasts

Question 9

Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the _____ membrane

Answer 9

thylakoid

Question 10

the space between the thylakoid and the chloroplast membranes is called the _____

Answer 10

stroma

Question 11

this looks like stacks of coins

Answer 11

thylakoid membranes

Question 12

where is the green pigment chlorophyll is located

Answer 12

in thylakoid membarne

Question 13

_______ is the major pigment used in photosynthesis

Answer 13

Chlorophyll A

Question 14

photosynthetic protists which are responsible for the “red tides” that often prompt warnings against eating shellfish, contain a variety of light-sensitive pigments, including both chlorophyll and the red pigments responsible for their dramatic coloration.

Answer 14

dinoflagellates

Question 15

In plants, the so-called “light” reactions occur within the ______________, where the aforementioned chlorophyll pigments reside.

Answer 15

chloroplast thylakoids

Question 16

the light-independent or “dark” reactions take place in the ____________.

Answer 16

chloroplast stroma

Question 17

what is ATP

Answer 17

Adenosine Triphosphate

Question 18

____________________ is the energy currency for cellular processes.

Answer 18

Adenosine triphosphate (ATP)

Question 19

_____ provides the energy for both energy-consuming endergonic reactions and energy-releasing exergonic reactions, which require a small input of activation energy.

Answer 19

ATP

Question 20

how many phosphate groups are there in ATP

Answer 20

three phosphate groups

Question 21

is a nucleoside consisting of the nitrogenous base adenine and the five-carbon sugar ribose.

Answer 21

Adenosine

Question 22

three phosphate groups

Answer 22

alpha, beta, and gamma

Question 23

The bond between the beta and gamma phosphate is considered “________” because when the bond breaks, the products [adenosine diphosphate (ADP) and one inorganic phosphate group (Pi)] have a lower free energy than the reactants (ATP and a water molecule).

Answer 23

high-energy

Question 24

ATP breakdown into ADP and Pi is called _____________ because it consumes a water molecule

Answer 24

hydrolysis
