Exam #3 Flashcards
Which of the following is an example of potential energy?
A chemical bond
While you are siting down to lunch we are consuming _
energy which will then be converted into_ energy as we work until dinner time?
Potential; kinetic
Which best describes the first law of thermodynamics?
Energy is not created nor destroyed, but it can change from one energy form to another.
Plants only absorb about 10% of the light the sun emits. The rest is unused. This is illustrative of the_
Second Law of Thermodynamics
The sub units from which ATP is made are_
ADP and phosphate
Which of the following is not true about ATP?
Living things produce most of it through photosynthesis
Life gains most of its energy from _
Sunlight
The light dependent reactions of photosynthesis take place in the _ while the light dependent reactions takes place in the _.
Thylakoid membrane; stroma
Why are plants green?
They reflect green wavelengths of light and absorb blue and red light.
Which of the following is the correct chemical reaction for photosynthesis?
Light + 6Co2+ 6H2o-> 6o2 + C6H12O6
What organisms are capable of photosyntheis?
Plants, algae, and some bacteria
During photosynthesis, visible light has enough energy to _
Excite electrons
Protons ( H+) accumulate in the thylakoid space during electron transport between photosystemsII and I. The excess of protons in the thylakoid space_.
Move from the thylakoid space to the stroma through an ATP synthase complex channel that generates ATP.
Which of the following is the correct equation for cellular respiration?
C6H12O6+ 6O2-> 6H2O+ 6CO2+ ATP
Which is most closely associated with the Calvin cycle?
Carbon Dioxide fixation
Which is the correct sequence for aerobic breakdown of glucose in cellular respiration?
None of the above
Glycolysis breaks_into two molecues of _.
Glucose; pyruvate
__is a product of the Calvin cycle that is used to form glucose, amino acids or fatty acids.
Glyceraldehyde-3-phosphates ( G3P)
Which of the following plant is an example of a CAM plant?
Pineapple
A product of photosynthesis,_, is the chief source of energy for most organisms.
Glucose
If the Calvin cycle uses three molecues of CO2 to produce six molecues of G3p ( glyceraldehydes-3-phosphate), but not only one G3P molecule is used to form a carbonhydrate molecue, what happens to the other carbon that were taken in?
The other five G3P molecules are used to regenerate more RuBP.
