Flashcards in Unit 8 Quiz Deck (29):
1

cellular respiration equation

C6H12O6 + 6O2 ----> 6CO2 + 6H2O + energy (ATP) (38 ATP total energy)

glucose + oxygen = carbon dioxide + water + ATP

2

CO2 production in embryos

CO2 + H2O ----> H2CO3 (Carbonic acid)

3

phenol red color change

red at neutral pH
yellow at acidic pH

4

fermentation (anaerobic process)

measure CO2

glucose ----> ethanol + CO2 + ATP

5

cellular respiration can be broken down into three sets of chemical reactions

1. glycolysis
2. kreb's cycle (citric acid cycle)
3. Electron transport chain (oxidative phosphorylation)

6

glycolysis

glucose + 2ATP = pyruvic acid + 4 ATP

7

glycolysis is an

anaerobic reaction.

8

glycolysis takes place in the

cytosol of the cell

9

for every 1 molecule of glucose you get the production of

2 new molecules of ATP.
(remember you had to use 2 to start the chemical reaction)

10

there are special types of glycolysis called

fermentation

11

alcohol fermentation

organisms such as yeast ferment the sugars in fruits or grains to make ATP for themselves.

12

The out come of alcohol fermentation is 3 products

carbon dioxide gas
ATP
ethyl alcohol

13

lactate fermentation

takes place in your muscle cells. When you are exercising strenuously or doing some aerobic activity and you push your muscles to their limit, then they will start creating more energy (ATP) by non-aerobic means.
The product of this reaction is lactic acid and results in very sore muscles

14

Kreb's Cycle

In the kreb's cycle Acetyl CoA combines with oxaloacetic acid to make citric acid. During this process ATP is made and also another energy rich electron carrier called NADH.

15

The kreb's cycle takes place in the

mitochondria of your cells in an area called the matrix.

16

The kreb's cycle turns

twice per molecule that enters it

17

Each turn of the kreb's cycle results in the formation of

1 molecule of ATP. So ... the kreb's cycle produces 2 molecules of ATP during its chemical reactions.

18

NADH is also produced in the kreb's cycle. It leaves the cycle and starts the

electron transport chain. It is the initial electron carrier.

19

Electron transport chain

This is an aerobic chemical reaction. It must have oxygen to run.

20

For every 1 molecule of glucose that we take in we get the production of approximately

32 molecules of ATP during this set of chemical reactions.

(electron transport chain)

21

The electrons are passed down a

chain of electron acceptors. The last acceptor in the chain is oxygen.

(electron transport chain)

22

The electron transport chain reactions take place in the

mitochondria of your cells in an area called the cristae

23

hydrogen ions (+) are used during this process (electron transport chain) to make the

ATP.

24

coloration of germinated

yellow

25

coloration of germinated-boiled

red

26

what does the term germination mean

a period of growth that follows a period of dormancy (nutrients/stimulation G factors are present)

27

At the end of your pea experiment, what colors did you expect to see for each set of peas? why?

boiled: red, no CO2 produced because no respiration

non-boiled: yellow, normal respiration= CO2 produced

28

What do these different colors mean in terms of product being produced or not being produced in each scenario?

red: CO2 not produced
yellow: CO2 present/produced

29

The experiment that you performed with yeast tested what kind of cellular process?

fermentation
