1. In the synthesis of collagen, the hydroxylation of proline and lysine occurs in which of the following?* (A) Golgi apparatus (B) Secretory vesicles (C) Rough endoplasmic reticulum (D) Smooth endoplasmic reticulum 2. A 12-year-old boy with muscular dystrophy is found to have a mutation of the gene that encodes the protein dystrophin. Genetic alterations in dystrophin lead to progressive muscular weakness because dystrophin provides structural support to the sarcolemma by binding which...

Which one of the four components of the adaptation process pertains to reception of sensory stimuli from internal and external environments? A. Assimilation B. Accommodation C. Association D. Differentiation - A. Assimilation is the reception of sensory stimuli from internal and external environments. Accommodation is the motor response to these stimuli.

2.1.7 Practice: Protein Structure, Function, and Synth esis Practice AP Biology Points Possible:25 Date: 1. Duchenne muscular dystrophy (DMD) is a degenerative disease that affects primarily mal e children of mothers with a family history of the disease. Affected children do not produce th e muscle protein dystrophin, which provides structural support for muscle cells. Absence of t his protein leads to weakening of the cell membrane, loss of homeostasis, and eventually cel l death.Ex...
