Science test on photosynthisis

Question 1

In photosynthesis what are the 2 major reactions that take place?

Answer 1

Light independent reactions
Light dependent reactions

Question 2

In cellular respiration what 3 steps are involved?

Answer 2

Glycolysis
Krebs cycle
Electron transport chain

Question 3

Decide which formulas are photosynthesis or cellular respiration

Answer 3

6 CO2 + 6 H2O + light ———– C6 H12 O6 + 6O2 = Photosynthesis
C6 H12 O6 + 6O2 ———— 6CO2 + 6H2 0 + ATP energy = Cellular respiration

Question 4

Where does the light dependent reaction take place

Answer 4

Thylakoid

Question 5

What is another name for the light independent reaction?

Answer 5

Calvin cycle/ dark reaction

Question 6

Question 10

Where does the Krebs cycle take place

Answer 10

Mitochondria

Question 11

Where does the electron transport chain take place

Answer 11

Mitochondria

Question 12

Glycolysis does not require oxygen in order to take place

Answer 12

True

Question 13

The Krebs Cycle requires oxygen in order to take place

Answer 13

True

Question 14

The Electron Transport Chain does not require oxygen in order to take place

Answer 14

False

Question 15

When we consume glucose (C6 H12 O6) our bodies break down into carbon, hydrogen, and carbon dioxide

Answer 15

True

Question 16

The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide and water into glucose and by doing this, oxygen is released

Answer 16

True

Question 17

Photosynthesis releases energy, energy needed to maintain our body temperature

Answer 17

False

Question 18

The energy released in respiration can be used to drive chemical reactions between sugars and other substances

Answer 18

True

Question 19

Amino acids are composed of carbon, oxygen, and fat bombs

Answer 19

False

Question 20

Cellular respiration is a chemical process in which the bonds of food molecules and oxygen molecules are broken down and new compounds are formed that can transport energy to muscles

Answer 20

False

Question 21

As we eat plants that have made their own glucose, the glucose we consume can be broken down and recombined into different products like amino acids

Answer 21

True

Question 22

Glucose broken down can be used to make larger molecules such as amino acids, proteins, or DNA

Answer 22

True

Question 23

Chemical reactions can create products that are more complex than reactants (the material you started with) for ex. Glucose being converted to a DNA molecule

Answer 23

True

Question 24

Light dependant reaction and light independent reaction takes place in the chloroplast

Answer 24

False
