Respiration in Plants- Quiz 3

Which metabolic pathway is a common pathway to both anaerobic and aerobic metabolism?

• TCA cycle

• ETS

• EMP pathway

• Kreb’s cycle

ATP is –

• An energy currency

• a nucleotide

• formed in both respiration and photosynthesis

• All

Glycolysis –

• Takes place in all living cells

• Causes partial oxidation of glucose (one molecule) to form 2 molecules of pyruvic acid and 2 ATP as net gain

• Uses 2 ATP at two steps

• All

Function of respiration is to –

• make ATP

• Make NADH

• Get rid of glucose

• Get rid of CO₂

Glycolysis is found in –

• Eukaryotic cells

• Anaerobic cells

• Virtually all cells

• Most muscle cells

How many molecules of O2 are used and how many CO2 comes out during the glycolytic breakdown of one glucose molecule?

• 1; 2

• 2; 1

• 0; 0

• 36; 6

Fermentation always produces –

• AMP

• NAD⁺

• Pi

• DNA

NAD⁺ is –

• a protein

• an oxidising agent

• a reducing agent

• formed under only aerobic conditions

In Kreb’s cycle, how many oxidation (dehydrogenation) occur?

• 4

• 6

• 2

• 1

Correct sequence of events in Kreb’s cycle is –

• Acetyl CoA →Citrate →Pyruvate →

  α -ketoglutarate →Succinate →Malate→ Fumarate→ OAA

• Acetyl CoA →Citric acid→α -ketoglutaric acid →Succinic acid →Fumaric acid→ Malic acid→ OAA

• Acetyl CoA →Citric acid →Malic acid →α-ketoglutaric acid →Succinic acid →OAA

• All are wrong
