Question 1

What is the chemical formula for glucose?

Answer 1

C6H12O6

Question 2

What is the difference between a product and a reactant?

Answer 2

A reactant is what goes into the equation a product is the outcome of the reactant.

Question 3

Where do the oxygen atoms come from that become part of the glucose molecule in photosynthesis?

Answer 3

The oxygen atoms come from the 6CO2 (carbon dioxide) and H2O (water)

Question 4

Where do the hydrogen atoms in glucose come from?

Answer 4

The hydrogen atoms in the glucose come from H2O (Water)

Question 5

In which type of cell do both biochemical reactions occur?

Answer 5

Plant cell

Question 6

In which specific organelles do these reactions occur?

Answer 6

The mitochondria and chloroplasts

Question 7

What is the function of ATP in the cell?

Answer 7

to store energy

Question 8

What is the relationship between cellular respiration and photosynthesis regarding reactants and products?

Answer 8

The products of cellular respiration are the reactants of photosynthesis, vice versa though light and energy don’t go through with this.

Question 9

What are ALL THE PRODUCTS and the AMOUNTS of each resulting from cellular respiration?

Answer 9

Carbon dioxide 6CO2, Water 6H2O and energy

Question 10

What is the energy source for photosynthesis?

Answer 10

The sun

Question 11

Describe ATP and ADP.

Answer 11

ATP has three phosphate groups and ADP has two phosphate groups.
ATP is an energy molecule, and ADP is created from ATP if you take off one of the three phosphate groups.

Question 12

What type of organism makes its own food? Example.

Answer 12

Autotrophs, example is a flower (Plants)

Question 13

What type of organism must consume food? Example.

Answer 13

Heterotrophs, humans

Question 14

Why do plant cells have both chloroplasts and mitochondria? List what the organelles do specifically.

Answer 14

The chloroplasts perform photosynthesis for glucose and the mitochondria performs cellular respiration for energy.

Question 15

Why did the BTB change from blue to yellow if the elodea was placed in the dark?

Answer 15

Because plants perform cellular respiration to get energy.

Question 16

Do the snails and elodea depend on each other in the light? Why or why not? In the dark? Why or why not?

Answer 16

They depend on each other in the light because the elodea takes in the CO2 from the snail to perform photosynthesis. They don’t depend on each other in the dark because they both are performing cellular respiration.

Question 17

What is combustion?

Answer 17

The process of burning a fuel in the presence of oxygen which produces heat and sometimes light.

Question 18

What are 4 things that combustion and cellular respiration have in common? Be specific?

Answer 18

1. They both require fuels. For respiration, its glucose. 2. They both produce CO2 and H2O and energy as products. 3. They both require O2 as a reactant. 4.They both give off energy.

Question 19

Chemical equation for photosynthesis

Answer 19

reactants; 6CO2+6H2O+Light products; 6O2+C6H12O6

Question 20

Chemical equation for cellular respiration

Answer 20

reactants; 6O2+C6H12O6

products; 6CO2+6H20+Energy

Question 21

If we are using methane as a fuel for combustion, what is the chemical equation? (It doesn’t have to be balanced.)

Answer 21

reactants; CH4+O2

products; CO2+H2O+Energy

Question 22

What are the reactants in a combustion reaction?

Answer 22

fuel and oxygen

Question 23

What are the products in a combustion reaction?

Answer 23

oxide(s)+energy
