What are the products of aerobic respiration?

Glucose and oxygen

Carbon dioxide and water

Lactic acid

Carbon monoxide

What are the products of anaerobic respiration?

Glucose and oxygen

Carbon dioxide and water

Lactic acid

Carbon monoxide

What type of respiration requires oxygen?

Aerobic

Anaerobic

Where in the cell does aerobic respiration take place?

Nucleus

Cytoplasm

Mitochondria

Cell membrane

Which organ excretes carbon dioxide?

Lungs

Liver

Heart

Kidney

When animals exercise with a lack of oxygen their muscles can form

lactic acid

alcohol

minions

oxygen

The correct word equation for aerobic respiration is

carbon dioxide + water (+ energy) → glucose + oxygen

water + oxygen → carbon dioxide + glucose (+ energy)

glucose + oxygen → carbon dioxide + water (+ energy)

glucose + water → carbon dioxide + water (+ energy)

The correct word equation for Anaerobic respiration is

glucose → lactic acid + oxygen

glucose → lactic acid (+ energy released)

glucose + oxygen → lactic acid (+ energy released)

lactic acid → energy released

In order to make Bread and Beer

cellular respiration takes place

Oxygen and glucose are the reactants

Lactic Acid Fermentation is the product

Alcoholic Fermentation is the product

10.

Anaerobic means

oxygen is not required

oxygen is required

up to 38 ATPs are made

cellular respiration

11.

Which organism uses Aerobic Respiration?

Bacteria

yeast

muscle cells

Animals

12.

Why is yeast used to bake bread?

The waste gas, CO_2, makes bread rise

The alcohol produced makes bread dangerous

The yeast consumes O₂, causing bread to rise

13.

A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event

As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.

As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.

The cells will never run out of oxygen if the weightlifter is breathing.

As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.

14.

What are the uses of the energy produced in respiration? Tick all that apply.

To build larger molecules from smaller molecules.

To break down smaller molecules into larger molecules.

To maintain our body temperature.

To allow muscles to contract.

15.

After intense activity, your muscles feel sore because of

the accumulation of NAD+

the accumulation of lactic acid

the accumulation of ATP

the accumulation of carbon dioxide
