Q3 IB Bio Review

Cellular Respiration

100

Which form of respiration needs no oxygen?

Anaerobic respiration.

200

Which form of respiration forms the MOST ATP energy?

Aerobic respiration.

300

ATP stands for: 

Adenosine Triphosphate

400

State the equation for the fermentation of alcohol in anaerobic respiration.

C₆H₁₂O₆ --(yeast)--> 2C₂H₅OH + 2CO₂ + 2ATP

500

State the equation for the fermentation of lactic acid in anaerobic respiration.

C₆H₁₂O₆ ---> 2C₃H₆O₃ + 2ATP

Photosynthesis

100

Plant cells perform photosynthesis in the _____.

chloroplast

200

Light intensity ______ affects CO2 uptake?

Exponentially/Linearly/Logarithmically/Inversely

Logarithmically

300

State the chemical equation for photosynthesis.

6CO₂ + 6H₂O --(light)--> 6C₆H₁₂O₆ + 6O₂ 

400

Describe why plants are green.

Plants are green because they are most photosynthetically active in red and blue light. They are least photosynthetically active in green light. Therefore they absorb red and blue light but reflect green light. 

500

In a Thin Layer Chromatography experiment, what is the mobile phase and what is the stationary phase? Which one is polar and which one is non-polar?

Stationary phase = Paper = Polar

Mobile phase = Solvent = Non-polar

DNA Replication

100

The mechanism of DNA replication is known as -

semi-conservative.

200

What is the name of the scientists that proved DNA replication is semi-conservative?

Meselson and Stahl

300

3' AGTCGTAAT 5'

5' TCAGCATTA 3'

400

DNA replication occurs in the ____ phase of the cell cycle.

S-phase (Synthesis phase)

500

What is the name of the enzyme that makes new strands of DNA using the two old parent strands as templates?

DNA polymerase

DNA Transcription

100

Transcription is the process of transcribing DNA into ____.

RNA

200

RNA has what four bases?

Adenine, Cytosine, Guanine, Uracil

300

Transcribe the following DNA strand:

5' AGT CGT AAT TAG 3'

3' UCA GCA UUA AUG 5'

400

What are three differences between DNA and RNA?

DNA = 2 strands; RNA = 1 strand

DNA = deoxyribose pentose sugar; RNA = ribose pentose sugar

DNA = A,G,C,T; RNA = A,G,C,U

500

DNA sense sequence: ACT GGC AAT

DNA antisense sequence: TGA CCG TTA

mRNA strand: ACU GGC AAU

A set of three consecutive bases in RNA is known as a -

codon.

500

Translation occurs in what part of the cell?

Cytoplasm
