What is the difference between a triglyceride and phospholipid? -
correct answer-A triglyceride contains three fatty acids attached to
glycerol backbone, while a phospholipid has two fatty acids plus a
phosphate group attached to the glycerol
True or False: Active transport uses ATP to move components in parallel
with their concentration gradient, that is from a high concentration to a
low concentration - correct answer-False
What are the orphaned organelles orphaned from? - correct answer-
endomembrane system
True or False: It is a simple matter for a vesicle to form from the
endoplasmic reticulum - correct answer-False
, Explain the evolutionary origin of mitochondria - correct answer-It is
thought that a primitive proto-eukaryote engulfed a primitive proto-
prokaryote good at making ATP and this organism lived inside this larger
cell and began making ATP for the cell(endosymbiosis theory)
True or False: A single pass trans-membrane protein that is an alpha
helix can make a channel - correct answer-False
Explain how the vesicles are carried from the Golgi apparatus to the
plasma membrane - correct answer-Proteins are synthesized by
ribosomes and enter the rER. Vesicles bud off from the rER and carry
proteins to the Golgi apparatus; the Golgi apparatus modifies proteins;
and the vesicles bud off from the Golgi and carry modified proteins to
the plasma membrane
True or False: The ER is contiguous with the Golgi apparatus - correct
answer-False
