G7 Science Ch3.2

cellular respiration

QuestionAnswer
Define cellular respiration the process by which cells break down glucose & other molecules from food, using oxygen, and release energy
What is breathing? the process of moving air in AND out of your lungs. It brings oxygen into lungs and removes waste products of cellular respiration from your body.
Explain stages of cellular respiration 1)cytoplasm: glu broken down into sm particles & a little energy released. 2)mitochondria: molecules broken down more + use O2 to release great deal of energy
Cellular respiration equation C6H12O6 + 6 O2 ——> 6 CO2 + 6 H2O + energy
Name raw materials for cellular respiration glucose and oxygen
Animals get glucose from ____________ the foods they consume
Plants get glucose from ___________ photosynthesis, which they produce themselves!
Who carries out photosynthesis? producers
Who carries out cellular respiration producers & consumers
Fermentation an energy releasing process that does NOT require oxygen.
Which releases more energy, cellular respiration or fermentation? cellular respiration
Explain alcohol fermentation breakdown of glu w/o O2 in yeast or single celled organisms that produces alcohol + CO2 + little energy
Explain lactic fermentation muscle cells break down glucose w/o O2 and produce lactic acid + some energy
Plants capture energy by ?(cellular respiration/photosynthesis/fermentation) photosynthesis
Define autotrophs plant or other organisms who make their own food
Fermentation releases some energy (< cellular respiration) and lactic acid
Plants release energy by way of ?(cellular respiration/photosynthesis/fermentation) cellular respiration
Plants get energy when O2 reacts with ________ glucose; C6H12O6
A swimmer gets energy by way of ?(cellular respiration/photosynthesis/fermentation) cellular respiration (since they usu breathe even when swimming!)
Humans are _________ because they get energy __________ heterotrophs; the food they eat
If a swimmer drowns, he will initially get energy by way of ?(cellular respiration/photosynthesis/fermentation) lactic acid fermentation
Compare the raw materials of photosynthesis and Cellular respiration photosynthesis uses Carbon dioxide and water whereas Cellular respiration requires glucose and oxygen
In which organelles does cellular respiration occur? mitochondrion
____________ is a process that releases energy in cells without using oxygen fermentation
Name foods made with the help of fermentation bread, beverages such as beer and sparkling wine, sparkling grape juice
What is the source of energy used in photosynthesis (glucose/sunlight/ chlorophyll/ DNA) chlorophyll

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
