Question

24) Which free encrgy diagram represents the below reaction? 24) ADP PiATP Ho 25) 25) Hydropathy analyses are used to predict the structure of membranc prolcins. A positive index indicates a hydrophobicity, while a negative value indicates a hydrophilic region. A hydropathy analysis was done on a Golgi receptor protein, Sic2p, that is localized to the Golgi, ie. this receptor protein resides on The Sie2p protein has an N-terminal start-transfer sequence within its primary structure the Golgs True or False?t: Using both the above information and the hydropathy analysis shown below, the N erminus of the Ste2p protein will extend into the cytoplasm, while the C-tcrminus will reside within the Golgi lumen. B) A) False True 26) The concentration of solules in a red blood cell is about 2%, Red blood cells contain almost no mannose (CH.:0) or carbamide (CON.H.). Mannose cannot pass through the membrane, but water and carbamide can. Osmosis would cause red blood cells to shrink the most when immersed in solutions? A) a hypotonic mannose solution B) a hypotonic carbamide solution C) a hypertonic mannose solution D) pure water E) a hypertonic carbamide solution 27 ) An enzyme is a type of A) lipid B) carbobydrate C) protein D) nucleic acid E) stcroid

Explanation / Answer

24) Diagram B represents the above reaction condition here free energy of the product is higher than reactant so the reaction is not spontaneous and extra energy neede to drives the reaction in the form of Pi (inorganic phosphate ).

25) True , because signal sorting sequences present at N- terminal which get first bind to glogi receptor protein so N-terminal must be inside the cytoplasm.

26) a Hypotonic carbamide solution

27) Enzyme is a type of protein

28) true, photoautotrophs harvesting the light energy to chemical enrgy which is capable to convert inorganic carbon to organic carbon for example photosynthesis.

30) False, cystic fibrosis is a disorder where CFTR receptor is mutated and Cl- ions channels are affected not airway

31) D option is right

32) Non-competitive enzyme inhibition affect Vmax only and it lowers the Vmax .

33) C option is right
