Flashcards in Biology 11/30 Deck (20):
1

Name the three types of RNA and their function

mRNA: carriers genetic material the nucleus to the ribosome
tRNA: brings amino acids to ribosomes
rRNA: forms ribosomes

2

What is a codon?

3 nucleotides = 1 codon

3

What organelles make proteins ?

Ribosomes

4

What chemical process provides most of the energy used by life on earth?

Photosynthesis

5

Photosynthesis equation?

co2 HO2 sunlight C6H1206 O2

6

What are two traits of lights dependent reactions?

Can only occur in the daytime
Fills battery molecules with the energy from sunlight

7

What are two traits of both light dependent and independent reactions?

Transfers solar energy into chemical energy

Occurs only in producers

8

What are two traits of light independent reactions?

Can occur in daytime or night

Empties the energy of battery molecules into sugar

9

What is the function of light in photosynthesis?

Energizes electrons

10

In what organelle does photosynthesis occur?

Chloroplast

11

Example of long term and short term molecule

Long term: sugar
Short term: ATP

12

In what organelle does cellular respiration occur?

Mitochondria

13

Cellular respiration equation ?

C6H12O6 O2 CO2 H2O

14

Difference between aerobic and anatomical respiration?

aerobic requires oxygen and anaerobic does not

15

What kind of fermentation does yeast use?

Alcoholic

16

What produces the most ATP from a single sugar molecule?

Aerobic

17

What converts NADH back into NAD+, without collecting energy?

Fermentation: anaerobic

18

Splits a 6 carbon sugar into two 3 carbon molecules, and produces 2 ATP

Glycolysis: anaerobic and aerobic

19

Converts NADH into ATP

Electron transport chain: aerobic

20

Recycles 3 carbon product of glycolysis by splitting carbon-carbon bonds and releasing energy. Also produces co2

Kreb's cycle aerobic
