Photo-synthesis
6CO2+6H20 => C6H12O6+6O2
Byproducts of fermentation may include ( alcohol / citric acid) or lactic acid. Fermentation yields (much less / much more) ATP than the electron transport chain.
Alcohol : Much less
What describes the conversion of ADP to ATP?
an input of energy to attach a third phosphate group
The general process that the Krebs cycle is a part of, which uses oxygen to generate large amounts of ATP.
Cellular respiration
What sports does Mrs. K coach?
Cross Country and Golf
What best describes the role of light in the overall process of photosynthesis?
Light provides the energy for assembling small molecules into sugars.
Natasha is making a model of cellular respiration. Her model shows the pathway followed when there is enough oxygen available. What does Natasha’s model show?
an aerobic pathway consisting of glycolysis, the Krebs cycle, and the electron transport chain
Mariana eats an orange. Which statement describes the ultimate source of the energy that her body receives when she digests the orange?
The light energy that originates from the sun provides the energy to grow oranges, which contain macromolecules.
Savannah is asked to explain the locations of the stages of cellular respiration. What location should she give for the site of the Krebs cycle reactions?
the matrix of the mitochondria
What is Mrs. K's female dogs name?
Claire
Stuart is listing the changes to matter and energy that occur during the process of photosynthesis. Which of these examples should he include in his list?
changes that convert light energy into chemical energy stored in carbohydrates
Under normal conditions, gases diffuse through small holes in the leaves of a plant. When the weather is very hot and dry, plants may close these openings to conserve water. How are the closures most likely to affect photosynthesis?
They decrease the rate of photosynthesis by preventing carbon dioxide from entering the leaf.
The molecules in the food we eat contain chemical energy stored in chemical bonds. Which statement BEST explains how this energy is released?
Chemical bonds in food molecules are broken, releasing energy and allowing cells to use the energy to make ATP.
The Krebs cycle consists of many small steps, each catalyzed by a protein enzyme. What is another name for the Krebs cycle?
the citric acid cycle
What is Mrs. K's male dogs name?
Chance
Yasmine is asked to describe the structural organization of chloroplasts. She writes the following sentence:
“A chloroplast contains thylakoid stacks, called stroma, that are surrounded by fluid-filled grana.”
Which change to the sentence is necessary to make the sentence accurate?
Exchange the positions of “stroma” and “grana.”
Glycolysis is the first stage of cellular respiration and is an anaerobic process. During glycolysis, glucose is converted to two molecules of pyruvic acid. How is glycolysis kept functioning during cellular respiration?
Two molecules of ATP from the cell are invested at the beginning of the process of glycolysis.
In the process of glycolysis, four ATP molecules are synthesized from four ADP molecules. Why does glycolysis not yield four molecules of ATP?
Two ATP molecules are required to start the process.
This is an alternative, more official name for the Krebs cycle, referring to its primary starting and ending molecule.
the citric acid cycle
How tall is Mrs. K?
5'8"
Daniel is developing a model of the light-independent reactions of photosynthesis, also known as the Calvin cycle. How should the model show how carbon compounds enter and exit the cycle?
enter as carbon dioxide, exit as 3-carbon molecules
Xavier and Jill are practicing the 100-meter sprint. Which statement BEST describes the metabolic pathways their muscles will utilize to produce the quick energy needed for this intense exercise?
Glycolysis begins glucose metabolism, and in the absence of oxygen, lactic acid fermentation takes over.
Glycolysis yields ______ molecules of ATP per glucose molecule, while the electron transport chain yields ______ molecules of ATP due to the presence of oxygen.
2 : 32
This 2-carbon molecule is the direct fuel that enters the cycle.
Acetyl-CoA
What food does Mrs. K NOT like?
Seafood
