How many turns of the Calvin cycle are required to create one molecule of glucose in a C3 plant?
2
Because of the chemiosmotic concentration gradient, the net movement of H+ ions will move ______________________ to power ATP synthase.
A to B
Which products from the LDR are required for the Calvin cycle?
ATP and NADPH
The light reactions of photosynthesis supply the Calvin cycle with which of the following?
ATP and NADPH provide the power and raw materials for the Calvin Cycle.
In the absence of oxygen, yeast cells can obtain energy by fermentation, resulting in the production of:
ATP, CO2, and ethanol (Ethyl alcohol)
After strenuous exercise, a muscle cell would contain decreased amounts of __________ and increased amounts of __________.
ATP; lactic acid
The role of pigments is to
Absorb light energy to excite electrons
The primary role of oxygen in cellular respiration is to:
Act as a receptor for electrons and hydrogen, forming water
A plant that closes its stomata during the day to maintain moisture in the cells and uses CO2 from respiration would undergo which type of plant?
CAM
Which phase of photosynthesis produces three carbon sugars? (G3P)
Calvin Cycle
What is the term for metabolic pathways that release stored energy by breaking down complex molecules?
Catabolic pathways
Photosynthetic organelle that includes thylakoid discs and stroma as part of its internal structure.
Chloroplast
Which of the following is NOT a receptor on the surface of a cell?
Cyclic AMP
Experimental evidence shows that the process of glycolysis is present and virtually identical in organisms from all three domains: Archaea, Bacteria, and Eukarya. Which of the following hypotheses could be best supported by this evidence?
Glycolysis is a universal energy-releasing process and therefore suggests a common ancestor for all forms of life
What is the role of CO2 in photosynthesis?
It uses the carbon atoms to add to RuBP
All of the following processes produce ATP EXCEPT
Lactic acid formation
Which molecule produced by glycolysis is used to start the citric acid cycle.
Pyruvate
What is the function of ATP Synthase?
This enzyme uses H+ ion concentration gradient to help build ATP
Which of the following probably evolved first?
glycolysis
Where does the Calvin cycle take place
stroma of the chloroplast
The ATP produced during glycolysis is generated by which of the following?
substrate level phosphorylation
The figures below illustrate the similarities between ATP synthesis in mitochondria and chloroplasts. The figures can best assist in answering which of the following questions?
Do electron transport chains create a gradient so that ATP synthase can create ATP molecules?
Transpiration is a result of special properties of water. The special properties of water include all of the following EXCEPT:
Hydrophobicity
The organelle present in nearly all eukaryotic cells. Some metabolic steps of cellular respiration are catalyzed in its inner membrane.
Mitochondria
An experiment to measure the rate of respiration in crickets and mice at 10oC and 25oC was performed using a respirometer, an apparatus that measures changes in gas volume. Respiration was measured in ml of O2 consumed per gram of organism over several five-minute trials and the following data were obtained. According to the data, the crickets at 25oC have greater oxygen consumption per gram of tissue than do the crickets at 10oC. This trend in oxygen consumption is the opposite of that in the mice. The difference in trends in oxygen consumption among crickets and mice is due to their3resp%20data2.jpg
Mode of internal temperature regulation
CAM plants keep their stomates closed during the daytime to reduce excess water loss. They can do this because they
can incorporate CO2 into organic acids at night
Which process of cell respiration is most closely associated with intracellular membranes?
oxidative phosphorylation
In addition to ATP, what is produced during glycolysis?
pyruvate and NADH
