Question

52. This classification of membrane protein allows for the passage of a particul molecule or ion into a cell, but it only works in a passive fashion because it is always open: A. Receptor protein B. Enzymatic protein C. Channel protein D. Carrier protein 53. Which of the following is NOT a difference between DNA and RNA? A. DNA is double-stranded; RNA is single-stranded B. DNA has the base thymine; RNA has uracil C. DNA has deoxyribose sugar, RNA has ribose sugar D. DNA is held together along sugars; RNA along phosphates 54. Why do sex-linked disorders occur more frequently in males than in females? A. Gene for disorder is located on Y chromosome B. Testosterone activates disorder genes C. Recessive alleles on X chromosome are exposed since males have only one X D. Y chromosomes activate disorder genes on X chromosomes 55. This process utilizes the energy released when hydrogen ions flow down their concentration gradient to manufacture ATP. It happens in mitochondria during oxidative phosphorylation and in chloroplasts during parts of the light reactions: A. Chemiosmosis B. Diffusion C. Substrate-level phosphorylation D. Synthesis 56. If you were reading an article on a new discovery in genetics, and the researcher reported that the trait they were studying was controlled by several genes-polygenic inheritancewhat would be the pattern you would expect to see in the trait studied? A. Two trait states; one dominant, one recessive B. Several trait states, but each in a definitive category (like blood type) C. Differing trait states in men and women D. A continuous range of trait states with no discrete categories 57. Rough Endoplasmic Reticulum: 1) Associates with ribosomes 2) Processes and modifies proteins 3) Synthesizes lipids 4) Is continuous with the outer nuclear envelop A. 1 & 3 B. 2 & 4 C. 1, 3, and4 D. 1,2, and 4

Explanation / Answer

Answer

52. The correct option is C. Channel Protein. Channel proteins always work in passive fashion.

53. The correct option is D. Both DNA and RNA has sugar-phosphate backbones.

54. The correct option is C. Since malesmales have one X chromosome in one Y chromosome. The sex-linked disorder gets exposed

55. The correct option is A. Chemiosmosis.

56. The correct option is B. This is a common phenomenon in blood group as blood group is polygenic.

57. The correct option is C. 1, 3, and 4. Processing and modification of proteins happens in the golgi apparatus.
