Ch 9

Question 0

What is a calorie, Calorie

Answer 0

A capital C calorie is 1000 lowercase c calories

Question 1

Why’s food important

Answer 1

It provides us with the chemical building blocks to grow and reproduce and energy

Question 2

What is cellular respiration

Answer 2

The process in which the body releases energy by breaking down glucose and other food molecules in the presence of oxygen

Question 3

What is cellular respiration’s chemical formula

Answer 3

Six CO2 + C6 H 12 O 6—> six CO2 +6 H2O plus energy

Question 4

What does cellular respiration produce

Answer 4

ATP

Question 5

How many steps are in cellular respiration

Answer 5

Three

Question 6

What is glycolysis

Answer 6

The process by which one molecule of glucose is broken down into 2 3 carbon compounds called pyruvate or pyruvic acid

Question 7

Where does glycolysis take place

Answer 7

The cytosol

Question 8

Why is glycolysis special

Answer 8

It does not require oxygen

Question 9

What is the net yield of glycolysis

Answer 9

2 ATP and 2 NADH molecules

Question 10

Why do we need other steps other than glycolysis

Answer 10

Because in a few seconds all of the cells NAD+ are filled with electrons in glycolysis cannot continue

Question 11

What is the next step after glycolysis

Answer 11

If oxygen is not present it goes into fermentation if oxygen is present it doesn’t to cellular respiration

Question 12

What must be present in order aerobic respiration take place

Answer 12

Oxygen

Question 13

What are the two stages of the aerobic respiration

Answer 13

The Krebs cycle and the electron transport chain

Question 14

What is the Krebs cycle

Answer 14

Acetyl coA is broken down into CO2 well energy is released

AKA The citric acid cycle

Question 15

Where does the Krebs cycle take place

Answer 15

The mitochondrial matrix

Question 16

What is the net yield of the Krebs cycle

Answer 16

Six NADH 2 FADH2 2 ATP and 4 carbon dioxide

Question 17

What powerful electronic scepter is used to use the energy in pyruvic acid

Answer 17

Oxygen

Question 18

Where is the electron transport chain located

Answer 18

The mitochondrial cristae

Question 19

What does the electron transport chain do

Answer 19

Transports electrons to oxygen

Question 20

What is chemi osmosis

Answer 20

Hydrogen ions move through the ATP synthase and spin the ATP synthase allowing ADP and a phosphate to equal ATP

Question 21

What is the net yield of the electron transport chain

Answer 21

Every NADH produces three ATP and every FADH2 produces 2 ATP equaling 34

Question 22

How many ATP are produced from one glucose molecule

Answer 22

38

Question 23

Why does the process of cellular respiration lose two ATP

Answer 23

Some ATP is used to pump NADH from glycolysis into the mitochondria

Question 24

How efficient are we and getting energy

Answer 24

38% efficient the rest is lost as heat

Question 25

What is fermentation also known as

Answer 25

Anaerobic respiration

Question 26

Where does fermentation take place

Answer 26

In the cytosol

Question 27

Why is fermentation important

Answer 27

Although ATT is not produced it allows for NAD+ to be regenerated so glycolysis can go on

Question 28

What carries out the lactic acid fermentation

Answer 28

Micro organisms

Question 29

What is lactic acid fermentation used for

Answer 29

To make food products

Question 30

What happens during exercise

Answer 30

Your muscles used up available oxygen faster than it can be delivered, when this happens so swap to lactic acid fermentation

Question 31

What happens to muscles during lactic acid fermentation

Answer 31

Two months lactic acid leads to muscle cramps, eventually are lactic acid is given to the liver where it is going vertical back to pyruvic acid

Question 32

What is alcohol fermentation

Answer 32

Some unicellular organisms and plant cells convert pyruvic acid into ethyl alcohol
