Exam 4

Question 1

NADPH

Answer 1

NADP+ + 2 e- and H+= NADPH

build macromolecules

Question 2

NADH

Answer 2

NAD+ + 2 e- and H+= NADH

take apart macromolecules

Question 3

Light reactions capture light energy

Answer 3

Take place in thylakoids
Use chlorophyll
Convert solar energy into chemical energy

Question 4

Calvin Cycle (Dark Reactions)

Answer 4

Occur in the stroma
Use the energy produced in the light reactions
Synthesize sugar from CO2 and H2O

Question 5

Light Reactions

Answer 5

Photosystem 2: water will be split into H+, O2, and electrons. These electrons will be what supplies the energy.
photosystem 1: the sun electrons move from P2 into the antenna complex of P1. Then they move into the ETC of P1 and during the ETC, NADPH will be created.
ATP synthase: last step in light reactions, enzymes that synthesizes ATP by using H+ from the splitting of water in P2.

Question 6

Aerobic

CR

Answer 6

Answer 7

Breaking down glucose

Question 8

Krebs cycle

Answer 8

Formation of energy carriers

Question 9

Oxidative phosphorylation

Answer 9

Use oxygen to produce ATP

Question 10

Similarities & Differences

Answer 10

PH.
- chloroplast
-plant cell
CR
-animal cell
-mitochondria
SAME
-Create ATP

Question 11

Base pairing

Answer 11

A-T

C-G

Question 12

DNA Replication

Answer 12

Hydrogen bonds broken
Strands unwind and separate
Each strand is a template for the other
Result is two identical copies

Question 13

DNA repair

Answer 13

Recognize
Remove
Replace

Question 14

1. Why is DNA replication semi conservative??

Answer 14

• It is semi conservative because it takes one old strand and one new strand to make up the double helix DNA strand, it happens for EACH original strand.

Question 15

Nucleotide

Answer 15

P-S-Nit. Base

Question 16

DNA

Answer 16

P-S-A T-S-P

P-S-C G-S-P

Question 17

Asexual

Answer 17

Prokaryotes divide through binary fission (identical daughter cells)

Question 18

Sexual

Answer 18

Eukaryote cell division is more complicated (daughter cells are NOT identical to parent cells)

Question 19

Adult Stem cell

Answer 19

can be grown and developed outside of the body; already have a “pre-destination”

Question 20

Embryonic

Answer 20

doesnt have destination

Question 21

Interphase

Answer 21

cell spends 90% of its life

Question 22

Mitosis

Answer 22

Prophase
 Prometaphase
 Metaphase   
 Anaphase
 Telophase
Cytokinesis: division of the cytoplasm
