Question

1. Put the following steps of aerobic cellular respiration in the correct order.

Below is a sequence of events. Place them in the order they should occur, number 1 being the first item. Select the step number from the drop down next to each item.

_ Acetyl CoA is moved into the mitochondria

_ Ingested food is broken down into glucose molecules

_ Electron carriers release energy through the Electron Transport Chain

_ Release of carbon dioxide during the Kreb's cycle

_ The 6 carbon sugar, glucose, is broken down into 3 carbon molecules

2.

Match the following metabolic processes with their terminal electron acceptors.

The task is to match the lettered items with the correct numbered items. Appearing below is a list of lettered items. Following that is a list of numbered items. Each numbered item is followed by a drop-down. Select the letter in the drop down that best matches the numbered item with the lettered alternatives.

a. Organic molecule

b. Oxygen

c. Inorganic molecule (not oxygen)

1. Fermentation

2. Anaerobic cellular respiration

3. Aerobic celluular respiration

Answer 1

The answer to the given question has been solved as under :

I) The order of events given as :

1. Ingested food is broken down into glucose molecules.

2. The 6 carbon sugar, glucose, is broken down into 3 carbon molecules.

3. Aceryle CoA is moved into the mitochondria.

4. Release of carbon dioxide during Kreb's cycle.

5. Electron carriers release energy through electron transport chain.

II)

Fermentation : organic molecule

Anaerobic cellular respiration : inorganic molecule other than oxygen

Aerobic cellular respiration : oxygen
