Cellular Respiration and Photosynthesis Test Flashcards
What food substance supplies energy to cells?
Glucose
What does ATP stand for?
Adenosene triphosphate
What is the function of ATP?
Carries energy from one part of a cell to another. (You can think of it as just being energy)
Name the parts of an ATP molecule.
Adenine, ribos, and phosphate groups
What is the difference between a drawing of an ATP and ADP molecule?
ATP will have 3 Ps (all in the same spot) and ADP will have 2 Ps (all in the same spot)
What happens to an ATP molecule when it releases energy?
Turns into ADP+P
What happens to an ADP molecule and P when it absorbs energy?
Turns into ATP
What does ADP stand for?
Adenosene diphosphate
Where is ATP made?
Mitchondrial matrix
Define aerobic reaction:
Needs oxygen (aerobic has the root word aero. which means air) (ex. hairspray is a type of aerosol)
Define anaerobic reaction:
Doesnt need oxygen
Why does cellular respiration produce more ATP than fermentation?
Glucose is completely broken down in cellular respiration but not in fermentation
What organism uses fermentation to obtain energy from glucose?
Yeast (and some bacteria)
Why are almost all anaerobic organisms only made of a single cell?
They don’t need as much energy as multi-celled organisms
Is the process of fermentation an anaerobic or aerobic reaction?
Anaerobic. It does not need oxygen.
Write the chemical equation for fermentation and know what is made.
somebody jus write it from their notes. bro….
Define cellular respiration
Breaking down glucose to make ATP using oxygen
Know the overall equation for cellular respiration
C6 H12 O6 ➡️ 6CO2 +6H2O
+38 ATP
What are the three stages of cellular respiration?
- Glycolysis
- Krebs cycle
- Electron Transport Chain (ETC)
Know if each stage of cellular respiration is anaerobic or aerobic
- Glycolysis: Anaerobic
- Krebs cycle: Aerobic
- ETC: Aerobic
Know where each stage of cellular respiration occurs
- Glycolysis: Cytoplasm
- Krebs cycle: Mitochondria Matrix
- ETC: Inner Mitochondria Membrane
Know what each stage of cellular respiration produces
- Glycolysis: 2 pyruvic acid, 2 NAHD, and 4 ATP
- Krebs cycle: 6CO2, 2 ATP, and 8 NADH+2FADH2
- ETC: 34 ATP and 6H2O
What stage of cellular respiration produces the most ATP
Electron Transport Chain
When would aerobic organisms carry out lactic acid fermentation? In what cells would this occur?
In muscle cells when they don’t get enough oxygen. Lactic acid builds up and causes pain.
