Photosynthesis + Cell Respiration Flashcards
What are the two products of cell respiration?
Water and carbon dioxide.
What is energy?
The ability to move an object for a distance. It cannot be produced or destroyed. It can only be transformed.
What are the products of photosynthesis?
Glucose and oxygen.
What is the chemical compound for glucose?
C6H12O6
What is an autotroph?
Organism that uses light as a source of energy and carbon dioxide as a source of carbon.
What is the name of organisms that use organic compounds as a source of energy and carbon?
Heterotrophs.
Active transport, motion and locomotion and chemical reactions are actions that can only produced with…
ATP. Adenosine Triphosphate.
True or false: The colour that you see is the pigment that is absorbed by the chlorophyll.
False. All the other colours are absorbed while the colour that you see is reflected.
What is grana?
A stack of thylakoid membranes. Their cytoplasm is called lumen and they are found in the stroma of the chloroplasts.
What is embedded in the thylakoid membrane?
Chlorophyll. Chloroplast’s pigment.
Where do light dependant reactions occur?
Thylakoid membrane + lumen (grana)
Where do light independent reactions (Calvin cycle) occur?
Stroma.
What is the ATP and NADPH net gain of glycolosis?
2 ATP and 2 NADPH.
Name the three steps of cell respiration, in order.
Glycolosis, Kreb’s Cycle, electron transport chain.
True or false: mitochondria have two membranes.
TRUE. They have an outer and inner membrane.
What are the two energy carriers in light-dependant reactions?
ATP and NADPH.
True or false: glycolosis requires oxygen.
FALSE. Glycolosis can occur without oxygen, the process is called fermentation. However Kreb’s cycle and the electron transport chain require oxygen to produce energy.
What are the two types of fermentation?
Alcoholic fermentation (ex: yeast) and lactic acid fermentation (ex: muscle pain)
Where does cell respiration occur?
In the mitochondria.
What are the names of the high energy electron carriers in cell respiration?
ADP and NADH
After glycolosis, the glucose compound has been converted into two _______.
Pyruvic acid.
What does anaerobic mean?
“Not in air.”
What is the name of the compound that is a 2carbon acetyl group combined with a 4 carbo molecule?
Citric acid (Kreb’s cycle)
What is the net gain of ATP during the complete process of cell respiration?
34/36.
