Total questions: 10
Worksheet time: 3mins
In which structure of the chloroplast does the chlorophyll contained?
A. Thylakoid
B. Stroma
C. Mesophyll
D.Granum
Comparable to mitochondria, which serves as a “powerhouse” of the cell, a chloroplast makes the availability of energy for plants accessible except:
A. It generates large quantities of energy
B. It stores calcium for cell signaling activities
C. It is responsible also for transporting molecules
D. It provides its own food that then gets used to power the organism.
The body performs many processes that depend upon energy and could not occur without a supply of ATP. How does the energy from ATP power the cellular reactions?
a. The cellular processes are coupled to hydrolysis of ATP, an exergonic
process
b. Cellular processes are coupled to hydrolysis of ATP, an endergonic
process
c. Energy from ATP hydrolysis is stored in cellular chambers
d. ATP hydrolysis absorbs the remaining energy from formation of glucose-6-
phosphate
How is the energy released by ATP hydrolysis used to power other reactions in a cell?
a. A reactant of one reaction is “shared” and used to be also the same product of the second reaction.
b. Energetically favorable reaction links with an energetically unfavorable reaction.
c. A product of one reaction is “picked up” and used as a reactant in the second reaction.
d. Energetically unfavorable reactions link into a less energetically favorable reactions.
Which of the following reactions exemplifies the water-mediated breakdown of adenosine triphosphate?
a. ATP + O ⇋ ADP+Pi+H2 + energy
b. ATP + H2O ⇋ ADP+Pi+energy
c. ATP + ADP ⇋ ADP+H20+Pi+energy
d. ATP + H2O ⇋ ADP+Pi+O2+energy
Chlorophyll absorbs most light in which colors of the visible range?
a. Violet and green
b. Violet and red
c. Green and red
d. Blue and red
The part of the line bracketed by “b” shows how in the green and yellow part of the spectrum chlorophyll a absorbs hardly any light. By contrast, the highest point of the line (“a”) is where most light energy is absorbed (blue light). A second peak shows up in the red part of the spectrum at “c.”
a. True
b. False
c. Maybe
d. None of the above
Chlorophyll, a very important pigment for food production among plants dominates green as its color. What is the reason for this?
A. It absorbs green wavelengths
B. It reflects green wavelengths of light
C. An optical phenomena caused by transmission of light
D. It absorbs blue and yellow wavelengths combined to be green as a
result
Energy is released from ATP when _______________________.
a. a phosphate group is added
b. a phosphate group is removed
c. adenine bonds to ribose
d. ATP is exposed to sunlight
Where do the light-dependent reactions occur?
a. thylakoid
b. stroma
c. mesophyll
d. mitochondria
