Cellular Respiration

Unit 5: Biology study set for TVMSC

QuestionAnswer
Why do cell functions require energy?
How do organisms obtain energy from chemical reactions? Through Cellular Respiration.
How does energy pass through biological systems in both photosynsthesis and cellular respiration? Energy is created in Cellular Respiration and energy is used to transport nutrients and things during photosythesis.
What is ATP and what is it's role in metabolism? ATP is a form of energy and has Adenine, A ribose, and three phosphates. ATP is the currency for metabolism.
What does ATP stand for? Adenosine Triphosphate
What is the definition of metabolism? The sum of all chemical reactions in the body.
What is the ATP cycle? ATP is used and then becomes ADP. ADP then can regain a phosphate to become ATP.
What is the process of cellular respiration and what is it's purpose? The process of cellular respiration is Glucose goes in and ATP comes out. The purpose is to make ATP.
What is the function of Mitochondria? The mitochondria is where the 2,3,4 steps take place in aerobic cellular respiration.
What are the two basic types of cellular respiration and the products they produce? The two types of cellular respiration are aerobic and anaerobic. Aerobic: Carbon Dioxide, Water, and 30-40 ATP. Anaerobic: Lactic Acid/Carbon Dioxide and Ethyl Alchohol, and 2 ATP
What is the difference between aerobic and anaerobic metabolism? Aerobic is much more efficent and gives you much more ATP.
Why are photosynthesis and cellular respiration so critical to life on Earth? Everything needs energy to do anything.
How is photosynthesis related to cellular respiration and how animals obtain energy? The products for photosynthesis are the reactants for cellular respiration and vice versa.
What is the role of cellular respirationa and photosynthesis in the carbon cycle? Photsynthesis takes away carbon dioxide and Cellular respiration adds it.
What is the eqaution for aerobic cellular respiration? C6H12 + 6O2 ------> 6H20 + 6CO2 + ATP Glucose + Oxygen --------> Water + Carbon Dioxide + ATP
What are the first 2 steps of aerobic cellular respiration including the molecules that go in and out of each step? Use all the words on the study guide and define each one as you go. Step 1. Gylcolosis takes place in the cytoplasm and where the 6 carbon molecule, glucise is broken into two 3 carbon molecules called Pyruvic Acid and 2 ATP. Step 2. Conversion of Pyruvic Acid. Mitochondria. Pyruvic Acid ----> Acetyl CoA
Why must plants do cellular respiration?
What is the third step of aerobic cellular respiration including the molecules that go in and out of each step? Use all the words on the study guide and define each one as you go. Step 3. Kreb's/Citric Acid Cycle takes place in the mitochondria and Acetyl CoA goes in and Carbon Dioxide, Protons, Electrons, and NADH + FADH2. Main goal is to create NADH.
What is the last step of aerobic cellular respiration including the molecules that go in and out of each step? Use all the words on the study guide and define each one as you go. Step 4. Electron Transport Chain takes place in the inner membrane of the Mitochondria. The electrons power proteins to pump protons through to the intermembrane space. Protons then move with gradient through ATP Synthase this gives energy for ADP to get
Define Chemiosmosis Movement of ions across a semipermeable membrane doen their gradient.
Define Pyruvate Oxidation Conversion of Pyruvate into Acetyl CoA
Define Pyruvate 3 carbon acid naturally formed in Glycolosis.
Define Proton Gradient Protons move down their gradient through the membrane
Define NADH and FADH2 Electron carriers

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.
