Anaerobic Respiration Quiz

What is the main advantage of aerobic respiration? Of anaerobic respiration?

Anaerobic respiration lets organisms live in places where there is little or no oxygen, and aerobic respiration releases a lot of energy.

yeast

can use alcoholic fermentation for energy

alcoholic fermentation

fermentation in which pyruvic acid changes to alcohol and carbon dioxide

lactic acid fermentation

fermentation in which pyruvic acid from glycolysis changes to lactic acid

fermentation involves this, but not the other two stages of cellular respiration

glycolysis

NAD+

recycles during fermentation

anaerobic respiration

respiration in the absence of oxygen

Which of the following organisms can perform alcoholic fermentation? (1) yeast, (2) humans, (3) bacteria.

1 and 3

Compare aerobic and anaerobic respiration, and discuss the advantages of each.

Aerobic respiration requires oxygen and produces far more ATP than anaerobic respiration, and anaerobic respiration does not require oxygen and allows survival in habitats which lack oxygen.

What process produces fuel for motor vehicles from living plant products? What is the waste product of this process?

Alcoholic fermentation produces fuel for motor vehicles from living plants. The waste product from this process is carbon dioxide.

Explain why bread dough rises when it is set aside in a warm place.

Bread dough rises when it's set aside in a warm place because yeasts in bread dough use alcoholic fermentation and produce carbon dioxide gas. The gas forms bubbles in the dough, which cause the dough to expand.

Why is bread light and fluffy?

Bread is light and fluffy do to alcoholic fermentation. Yeasts in bread dough use alcoholic fermentation and produce carbon dioxide gas. The gas forms bubbles in the dough, which cause the dough to expand.

The small holes in bread are formed by bubbles of ____________ gas, which is produced by alcoholic fermentation in yeast.

CO2

Some plants and fungi and many bacteria do not need oxygen. (True or false)

False

Alcoholic Fermentation

In alcoholic fermentation, pyruvic acid changes to alcohol and carbon dioxide.

Lactic Acid Fermentation

In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid.

Which of the following is true about anaerobic respiration?

It is a very fast process. It allows organisms to live in places where there is little or no oxygen. It evolved before aerobic respiration.

Why is NAD+ so important in fermentation?

It is important in fermentation because NAD+ also forms from NADH, allowing glycolysis to continue making ATP.

Advantages of anaerobic respiration

It lets organisms live in places where there is little or no oxygen.

Compare and contrast lactic acid fermentation and alcoholic fermentation. Include examples of organisms that use each type of fermentation.

Lactic acid fermentation is when pyruvic acid from glycolysis changes to lactic acid and is used by muscles. Alcoholic fermentation is when pyruvic acid changes to alcohol and carbon dioxide and is used by bacteria.

Why do your muscles get sore after intense activity?

Muscles get sore after intense activity because of the build up of lactic acid.

what does fermentation recycle

NADP+.

Advantages of aerobic respiration.

Releases a lot of energy

Tanya is on the high school track team and runs the 100-meter sprint. Marissa is on the cross-country team and runs 5-kilometer races. Explain which type of respiration the muscle cells in each runner's legs use.

Tanya would use anaerobic because it produces energy faster and is good for short distances and Marissa would use aerobic more energy for a long period of time.

Fermentation

The process of making ATP without oxygen.

Name two types of fermentation.

The two types of fermentation include Lactic Acid Fermentation and Alcoholic Fermentation.

Both lactic acid fermentation and alcoholic fermentation begin with the same molecule. What is that molecule and where did it come from?

They both begin with pyruvic acid. It came from glycolysis.

fermentation

an important way of making ATP without oxygen

muscle cells

can use lactic acid fermentation for energy

In alcoholic fermentation

carbon dioxide is released.

ATP

energy in the cell

Alcoholic fermentation explains why your muscles are sore after intense exercise.true or false

false

Anaerobic respiration produces much more ATP than aerobic respiration. true or false

false

Most living things use glucose to make ATP from oxygen.

false

When did aerobic respiration evolve

it evolved after oxygen was added to Earth's atmosphere

In lactic acid fermentation

lactic acid is produced.

lactic acid

makes your muscles feel tired and sore after intense exercise

is anaerobic respiration a slow process
