Photosynthesis + Cell Respiration

Question 0

What are the two products of cell respiration?

Answer 0

Water and carbon dioxide.

Question 1

What is energy?

Answer 1

The ability to move an object for a distance. It cannot be produced or destroyed. It can only be transformed.

Question 2

What are the products of photosynthesis?

Answer 2

Glucose and oxygen.

Question 3

What is the chemical compound for glucose?

Answer 3

C6H12O6

Question 4

What is an autotroph?

Answer 4

Organism that uses light as a source of energy and carbon dioxide as a source of carbon.

Question 5

What is the name of organisms that use organic compounds as a source of energy and carbon?

Answer 5

Heterotrophs.

Question 6

Active transport, motion and locomotion and chemical reactions are actions that can only produced with…

Answer 6

ATP. Adenosine Triphosphate.

Question 7

True or false: The colour that you see is the pigment that is absorbed by the chlorophyll.

Answer 7

False. All the other colours are absorbed while the colour that you see is reflected.

Question 8

What is grana?

Answer 8

A stack of thylakoid membranes. Their cytoplasm is called lumen and they are found in the stroma of the chloroplasts.

Question 9

What is embedded in the thylakoid membrane?

Answer 9

Chlorophyll. Chloroplast’s pigment.

Question 10

Where do light dependant reactions occur?

Answer 10

Thylakoid membrane + lumen (grana)

Question 11

Where do light independent reactions (Calvin cycle) occur?

Answer 11

Stroma.

Question 12

What is the ATP and NADPH net gain of glycolosis?

Answer 12

2 ATP and 2 NADPH.

Question 13

Name the three steps of cell respiration, in order.

Answer 13

Glycolosis, Kreb’s Cycle, electron transport chain.

Question 14

True or false: mitochondria have two membranes.

Answer 14

TRUE. They have an outer and inner membrane.

Question 15

What are the two energy carriers in light-dependant reactions?

Answer 15

ATP and NADPH.

Question 16

True or false: glycolosis requires oxygen.

Answer 16

FALSE. Glycolosis can occur without oxygen, the process is called fermentation. However Kreb’s cycle and the electron transport chain require oxygen to produce energy.

Question 17

What are the two types of fermentation?

Answer 17

Alcoholic fermentation (ex: yeast) and lactic acid fermentation (ex: muscle pain)

Question 18

Where does cell respiration occur?

Answer 18

In the mitochondria.

Question 19

What are the names of the high energy electron carriers in cell respiration?

Answer 19

ADP and NADH

Question 20

After glycolosis, the glucose compound has been converted into two _______.

Answer 20

Pyruvic acid.

Question 21

What does anaerobic mean?

Answer 21

“Not in air.”

Question 22

What is the name of the compound that is a 2carbon acetyl group combined with a 4 carbo molecule?

Answer 22

Citric acid (Kreb’s cycle)

Question 23

What is the net gain of ATP during the complete process of cell respiration?

Answer 23

34/36.

Question 24

What is the matrix?

Answer 24

The space inside the inner membrane of the mitochondria.
