Biology Review Test 3

Question 1

What is chromatography

Answer 1

the process of seperating substance based on their size

Question 2

How did we use chromatography in the lab and what a real-life example of how this can be used?

Answer 2

We saw how far the particles moved on a piece of paper. This can be used by testing for drugs using urine

Question 3

What is the balanced formula for photosynthesis? How is this related to that of cellular respiration

Answer 3

6H2O + 6CO2 light equals C6H12O6 + 6O2

The result of photosynthesis is ATP. Cellular respiration is the opposite of this process.

Question 4

VanHelmont

Answer 4

plants don’t eat dirt and water

Question 5

Priestly

Answer 5

plants produce gas

Question 6

Ingenhousz

Answer 6

plants need light

Question 7

Tell me the difference and give me an example of autotroph and heterotroph

Answer 7

autotroph- self-feeder- plants

Heterotroph- other eater- animals

Question 8

What are pigments? Give three examples

Answer 8

Pigments are light-absorbing molecules.

1. Beta Carotene(orange)
2. Xanthophyll(yellow)
3. Chlorophyll a and b(green)
4. Tannin(brown)

Question 9

Why are plants typically green?

Answer 9

Plants reflect green

Question 10

Why do leaves change colors in the fall

Answer 10

They change color because the plants store the nutrients in the branches, there’s less sun, and the sugar reacts with the anthocyanins causing reddish colors.

Question 11

Tell and illustrate the difference between AMP, ADP, and ATP

Answer 11

AMP- one phosphate
ADP- two phosphates
ATP- three phosphates
drawing

Question 12

Summerize the light dependent reaction using key words

Answer 12

Uses light to create energy(glucose) for the cell

Question 13

Summerize the calvin cycle using key words

Answer 13

Uses the glucose and makes it usable for the plant

Question 14

What does glycolysis mean? Show a diagram for glycolysis

Answer 14

Breaks glucose in half by producing pyruvic acid and NADH

Question 15

How many ATP are produced in glycolysis, Krebs Cycle, ETC, and total?

Answer 15

36 total
Krebs Cycle- 2
ETC- 32
Glycolysis- 2

Question 16

What is the idfference between the amount of ATP produced with and without oxygen?

Answer 16

With oxygen produces 30 more ATP than without oxygen

Question 17

Summarize the electron transport chain

Answer 17

Uses the NADH, FADH, ADP, and O2 to power the ATP synthase to create ATP

Question 18

Summarize the Krebs Cycle

Answer 18

The Krebs Cycle uses citric acid and glucose to produce carbon dioxide, ATP, and energizes electrons

Question 19

Where does photosynthesis take place?

Answer 19

In plants- chloroplast

Question 20

Where does cellular respiration occur

Answer 20

in plants and animals- mitochondria

Question 21

What does pyruvic acid go into if there is no oxygen present? What are the two types?

Answer 21

It truns to fermentation

1. Lactic acid
2. Alcohol

Question 22

Illustrate the process of lactic acid fermentation. Where does this occur? For how long?

Answer 22

Pyruvic acid + NADH = Lactic acid + NAD+
Occurs in muscles
lasts until your body gets enough oxygen

Question 23

In what organisms does alcoholic fermentation occur? Give two examples

Answer 23

Yeast and alcoholic beverages

Question 24

Define anaerobic and aerobic

Answer 24

anaerobic is without oxygen

aerobic- with oxygen

Question 25

Be able to draw photosynthesis and cellular respiration

Answer 25

Drawings

Question 26

Calvin

Answer 26

discovered the Calvin cycle

Question 27

Krebs

Answer 27

discovered the Krebbs cycle
