BIOD 151/A & P 1 (Portage Learning) Final Exam



1 FINAL EXAM
1. List two organs contained in the abdominal cavity.

The abdominal cavity contains the stomach, intestines, spleen and liver

1. List two organs contained in the pelvic cavity.

The pelvic cavity contains the bladder, reproductive organs and the rectum

2. TRUE OR FALSE?
a. The purpose of cellular respiration is to produce ADP. (T or F) False- (ATP is produced, not ADP)
b. Peripheral proteins are found on the outer surface of a cell membrane. (T or F) True
c. Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T or F) False- (process is endocytosis)
d. Receptor-mediated endocytosis uses a signaling molecule from another cell, binding to the cell membrane to
bring about changes within the cell proteins. (T or F) - True
e. Endocytosis is a passive process. It does not require cellular energy expenditure. (T or F) False- (Endocytosis is
an active process and requires cellular energy)


2. TRUE OR FALSE?
a. Cellular respiration occurs in the mitochondria. (T or F) True
b. The purpose of cellular respiration is to produce ATP. (T or F) True
c. Integral proteins are only found on the inner surface of a cell membrane. (T or F) False- (Peripheral proteins are
found on the inner or outer surface of the cell membrane. Integral proteins span the entire length of the membrane.)
d. Endocytosis is the process that occurs to eject biomacromolecules from the cell. (T or F) False - Exocytosis
e. Pinocytosis uses a signaling molecule from another cell, binding to the cell membrane to bring about changes
within the cell proteins. (T or F) False- (This process is called receptor-mediated endocytosis or information transfer)


IN YOUR OWN WORDS, DISCUSS TAY-SACHS DISEASE. WHAT ORGANELLE
3.

WITHIN THE CELL IS IMPACTED? WHAT ARE THE SYMPTOMS OF THE DISEASE
AND WHY DO THEY OCCUR?
Tay-Sachs disease impacts the lysosome of the cell because a digestive enzyme in lacking. This leads to a toxic buildup
of toxic lipids in the brain that cannot be broken down. This can lead to disability and death.

YOU ARE OBSERVING TWO CELLS UNDER THE MICROSCOPE. THEY ARE THE
4.

SAME TYPE OF EUKARYOTIC CELL BUT ONE APPEARS MUCH LARGER. BASED
ON APPEARANCE ALONE, WHICH ONE WOULD YOU EXPECT TO BE CARRYING
OUT RESPIRATION AT A MORE ACTIVE RATE, THE LARGER OR SMALLER CELL?
EXPLAIN WHY.
The smaller cell would be carrying out respiration at a more active rate because its surface area to volume ration is
higher than that of the larger cell. When there is more surface are and less volume the small cell allows metabolic
processes in general to occur faster.


4. EXPLAIN AT LEAST TWO DIFFERENCES BETWEEN TYPE I AND TYPE II ALVEOLAR
CELLS.
Type I forms the very thin simple squamous epithelium of the alveoli within the junction of the capillaries; also, Type II
produce and secrete pulmonary surfactant which is needed throughout the alveolar surface; and, Type II cells can
divide to replace damaged Type I cells.
