A radioactively labeled protein is made by cells and followed through the various organelles in the secretory pathway. After six
hours, all of the radioactivity is still primarily in the Golgi apparatus. This suggests that theA radioactively labeled protein is made by cells and followed through the various organelles in the secretory pathway. After six hours, all of the radioactivity is still primarily in the Golgi apparatus. This suggests that theprotein was not translated by the ribosomes.protein does not possess a signal peptide for localization within the lumen of the rough endoplasmic reticulum.protein possesses a signal for localization within the Golgi apparatus.all of the above
C) protein possesses a signal for localization within the Golgi apparatus.
Explanation:
Protein targeting or sorting is a process by which synthesized proteins are transported to their appropriate localizations in the cell or outside it. Proteins can be targeted to the inner space of an organelle (such as Golgi apparatus or endoplasmic reticulum) or its membrane, plasma membrane, or to exterior of the cell via secretion.
Usually, protein contains signal sequence on the N terminus that is involved in destination targeting.
<h3><u>The Food webs are preferred over food chains for representing the flow of energy in an ecosystem for the following reasons:
</u></h3>
The food webs are higher in complexity when compared to food chains and also, in food web, more than one primary producers is present which increases the 'flow of energy' in the ecosystem.
Food web represents the real life better than the food chains do.
Food web shows many different paths through which the organisms can be connected.
The cerebrum is the part of the brain that is responsible for processing the sensory information, critical thinking and learning. It stores this information and processing centers make predictions for various conditions. The Wernicke’s area and Broca’s area represent the areas of language present in the cerebral cortex and are associated with language and speech.
