Glycolysis

Question 1

What is Oxidation?

Answer 1

is the loss of an electron or hydrogen atom which release energy in chemical reactions.

Question 2

What is Reduction?

Answer 2

is the gain of an electron or hydrogen atom which store energy in chemical bonds.

Question 3

In cellular respiration, carbons in glucose are ________ and oxygen is _________ to form water.

Answer 3

oxidized, reduced

Question 4

What is Aerobic Respiration?

Answer 4

Cellular process that requires
the presence of O2

Question 5

An example of aerobic respiration?

Answer 5

cellular respiration

Question 6

What is anaerobic Respiration?

Answer 6

Cellular process that does not use O2

Question 7

What is Obligate Aerobes?

Answer 7

are organisms that require oxygen to survive because they rely on aerobic respiration to produce energy. Without oxygen, they can’t grow or carry out their vital functions.

Question 8

Example of obligate aerobes

Answer 8

most animals, fungi

Question 9

What is Obligate Anaerobes?

Answer 9

Organisms that can only live in an
environment that has no O2

Question 10

Example of obligate anaerobes

Answer 10

Locked jaw

Question 11

What is Facultative Anaerobes?

Answer 11

Organisms that can perform aerobic
respiration when O2 is present and
survive in anaerobic conditions

Question 12

Example of Facultative Anaerobes

Answer 12

E. Coli

Question 13

All organisms use glucose as a primary source of energy,
except __________

Answer 13

chemoautotrophs

Question 14

What is CR?

Answer 14

a controlled method to harness and store the energy which would otherwise be lost as light and heat.

Question 15

The harnessed energy from CR is ultimately stored as….

Answer 15

Adenosine Triphosphate

Question 16

What is SLP ?

Answer 16

SLP is like a direct, quick way to make ATP

Glycolysis + Krebs

Question 17

What is OP?

Answer 17

OP is a slower, oxygen-dependent method that makes more ATP

Question 18

We Get Energy from ATP by
__________ the high- energy
bonds between the last two
____________ in ATP

Answer 18

breaking, phosphates

Question 19

______ and P are more
stable than _____.

Answer 19

ADP, ATP

Question 20

CR ________ energy (exergonic) in a _______ pathway

Answer 20

releases, catabolic

Question 21

What is C6H12O6 + 6O2 6H2O + 6CO2 + 36ATP

Answer 21

???

Question 22

What is Glycolysis?

Answer 22

Glycolysis is the first chemical pathway involved in the splitting of glucose.

Question 23

________ organisms only
go through glycolysis

Answer 23

anaerobic

Question 24

Where does glycolysis occur ?

Answer 24

Occurs in the cytoplasm of the cell (not the mitochondria)

Question 25

Glycolysis ends with..

Answer 25

2 net ATP molecules + 2 pyruvates (a 3 C molecule) +
2NADH

Question 26

Fermentation is in

Answer 26

Animal – Lactate (Lactic Acid)

Plants, Yeast, Bacteria – alcohol + CO2

Question 27

What is phosphorylation

Answer 27

The transferring of a phosphate group from a high energy compound (ATP) to ADP molecule.

Question 28

What is glycolysis?

Answer 28

The first stage of cellular respiration, the splitting of glucose.

Question 29

NAD is reduced into NADH, which means a hydrogen/oxygen atom is added

Answer 29

…

Question 30

NADH is OXIDIZEDES into NAD, which means it loses a hydrogen/oxygen atom

Answer 30

….

Question 31

Pyruvate oxidation happens

Answer 31

in the presence of oxygen and converts pyruvate into acetyl-CoA, producing NADH and CO₂.

Question 32

Fermentation occurs

Answer 32

without oxygen and converts pyruvate into lactate or ethanol (ALCOHOL), regenerating NAD⁺ but producing no additional ATP.

Question 33

Aerobic respiration means ____ ATP is produced

Answer 33

more

Question 34

Anaerobic respiration means _____ ATP is produced

Answer 34

less

Question 35

What is decarboxylation?

Answer 35

The removal of a carbon dioxide (CO₂) molecule from a compound, usually in metabolic reactions.
