Question
Q38. The equation, 6Co, + 6H0-. ???. + 60, describes which of the lowing processes? a) b) light reaction c) nitrogen fixation d) aerobic respiration osyn Q39. What is produced by the light reactions? a) Co, and ATP b) ATP and H20 c) Oz, ATP, and heat d) Or. ATP and NADPH Q40. Which of the following requires the input of both ATP and NADPH? a) electron transport through the thylakoid membrane b) the light reaction only c) the Calvin cycle only d) neither the light reaction nor the Calvin cycle Q41. What do we call molecules involved in long-distance signaling? a) kinases b) hormones c) response elements d) receptors Q42. Once bound to a signal molecule (ligand), this receptor becomes active and catalvzes the transfer of a phosphate group to itself or intracellular proteins. a) enzyme-linked receptor b) ligand-gated ion channel receptor c) mechanoreceptor d) thermoreceptor Q43. Following its initial activation, how does a G protein become inactivated? a) It spontaneously loses activity within a few seconds b) The G-protein a subunit GTP is hydrolyzed to GDP allowing reassociation of the G-protein subunit and ?? dimer c) The receptor becomes internalized d) The G-protein ? subunit is digested and recycled Q44 signals in their extracellular environment is the process through which cells can detect and respond to a) Cell sensation b) Cell communication c) Reception TransductionExplanation / Answer
A38- The equation describe the photosyntehesis.
A39- o2 ATP AND NADPH..EXPLANATION {FIRST MAJOR STEP IN PHOTOSYNTHESIS AS LIGHT ENERGY IS CONVERTED INTO CHEMICAL ENERGY AS ATP AND NADPH.
A40- CALVIN CYCLE- EXP {ATP and NADPH produce by the light reaction are used in the Calvin cycle to reduce CO2 to sugar.}
A41 HORMONES ... As hormones vary widely in molecular size and type and usually travel via the circulatory system to target cell in another parts of the body.
A42- a -{enzyme linked receptor}
A43- {B}
A44 CELL COMMUNICATION.-{ the process by which a cell detects and responds to signals in its environment.}
