Respiration

What is released during the second stage of respiration?

A lot of energy, and carbon dioxide and water are also made.

Fermentation

An energy-releasing process that does not require oxygen.

How are breathing respiration and cellular respiration related?

Breathing brings oxygen into your lungs, and oxygen is needed for cellular respiration.

What do organisms produce in respiration?

Carbon Dioxide

What do plants use in photosynthesis?

Carbon Dioxide

What leaves tiny holes in bread?

Carbon dioxide

What are the products of fermentation?

Carbon dioxide gas, alcohol, and a little bit of energy.

What happens during respiration?

Cells break down simple food molecules (such as sugar) and release the energy they contain.

True or False. There is one stage to respiration.

False. There are two stages.

Why do your muscles run out of oxygen?

If you have used them for a long time (for example, run fast for a long time).

Where does the first stage of respiration take place?

In the cytoplasm of the cell.

Where does the second stage of respiration take place?

In the mitochondria.

Where does fermentation take place?

In yeast and some other single-celled living things.

Photosynthesis and respiration form a cycle that does what?

It keeps the levels of oxygen and carbon doixide about the same in the Earth's atmosphere.

How much energy is released in the first stage of respiration?

Just a little energy.

What is the product of the type of fermentation where yyour muscles run out of oxygen?

Lactic acid. (This is why your muscles feel weak and sore.)

What do organisms use in respiration?

Oxygen

What do plants produce in photosyntheses?

Oxygen

What is needed for the chemical reactions of the second stage of respiration to take place?

Oxygen.

How are photosynthesis and respiration opposites?

Photosynthesis uses carbon dioxide, water, and energy and makes oxygen and sugar. Respiration uses sugar and oxygen, and gives off carbon dioxide, water, and energy.

What happens in the first stage of respiration?

Sugar from food is broken down into smaller particles.

Respiration

The process by which cells obtain energy from glucose (sugar)

Cellular respiration

The respiration process that takes place inside cells.

What happens in the second stage of respiration?

Ths small sugar particles are broken down into even smaller particles.

What do bakers use fermentation for?

To make bread.

True or False? Photosynthesis and respiration are the opposite of each other.

True

True or false? Respiration is how cells get energy from sugar.

True

True or false? Respiration takes place in both plant cells and animal cells.

True.

What is another type of fermentation?

WHen your muscles run out of oxygen.

Do cells of all living things carry out respiration continuously?

Yes. (They are always doing respiration.)
