Cellular Respiration

Question 1

Is the process of breaking down food to produce ATP (energy currency) in the presence of oxygen

Answer 1

Cellular Respiration

Question 2

What are the three stages of Cellular Respiration

Answer 2

Glycolysis, Krebs Cycle/Citric Acid Cycle, and Electron Transport Chain

Question 3

Where is glyco and lysis derived from

Answer 3

Glyco = Glucose
Lysis = Breakdown

Question 4

Occurs in the cytoplasm of the cell where molecules of Glucose are broken down into 2 molecules of Pyruvic Acid. Does not require oxygen.

Answer 4

Glycolysis

Question 5

Occurs in the matrix (space within the inner membrane) of the mitochondria. Involves aerobic (relates to oxygen) process. Pyruvic Acid from Glycolysis enters to form

Answer 5

Krebs Cycle/Citric Acid Cycle

Question 6

Where the final stages of cellular respiration occurs

Answer 6

Mitochondria

Question 7

Occurs in the folds of the Inner Membrane of the Mitochondria (Cristae). NADH and FADH2 enters this stage

Answer 7

Electron Transport Chain

Question 8

Process by which energy is released from glucose when oxygen is NOT available

Answer 8

Fermentation

Question 9

A biological process which converts sugars such as a glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products

Answer 9

Alcohol Fermentation

Question 10

A biological process which converts sugars such as a glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products

Answer 10

Alcohol Fermentation

Question 11

A metabolic process by which glucose and other six-carbon sugars are converted into cellular energy and metabolite lactate

Answer 11

Lactic Acid Fermentation

Question 12

Toward the end of a marathon, a runner notices that she is getting
tired and her legs are cramping. What is the reason for this

Answer 12

Lactic Acid Fermentation

Question 13

Which of the following performs cellular respiration?
a. Plants
b. Animals
c. Humans
d. All of the above

Answer 13

d. All of the above

Question 14

Which of the following produces ATP?
a. Fermentation
b. Photosynthesis
c. Aerobic Respiration
d. All of the above

Answer 14

d. All of the above

Question 15

What product from the Kerbs Cycle is waste from your body?

Answer 15

CO2

Question 16

Which of the following best describes the metabolic changes that
occur in the yeast cell?

Answer 16

Glycolysis will still happen. Pyruvate won’t form.
So, the yeast cell will undergo alcohol fermentation.

Question 17

What is the next stage after Glycolysis if there is no oxygen available?

Answer 17

Fermentation

Question 18

In which way are photosynthesis and cellular respiration different?

Answer 18

Photosynthesis uses carbon dioxide.
Cellular respiration produces carbon dioxide

Question 19

What are the products of cellular respiration?

Answer 19

: ATP and Carbon Dioxide

Question 20

What is the powerhouse of the cell?

Answer 20

Mitochondria

Question 21

How many net ATPs are produced in the first stage?

Answer 21

2

Question 22

What waste product is released during cellular respiration?

Answer 22

CO2

Question 23

What is the reduced form of NAD+?

Answer 23

NADH

Question 24

Cells produce ATP most efficiently in the presence of

Answer 24

Oxygen

Question 25

What is the outcome of Glycolysis?

Answer 25

Pyruvic molecules

Question 26

n the presence of oxygen, cellular respiration occurs in two stages.
They are:

Answer 26

Krebs Cycle and ETC

Question 27

When oxygen is present, which molecule is coming from the Pyruvate?

Answer 27

Acetyl — CoA

Question 28

Where does the Krebs cycle occur?

Answer 28

Mitochondria Matrix

Question 29

Which organism produces its own food/glucose?

Answer 29

Autotrophs

Question 30

Where in the cell does Glycolysis take place?

Answer 30

Cytoplasm

Question 31

Which process produces the most ATP per molecule of glucose?

Answer 31

Aerobic Respiration
