Cirele th using your lecture notes, your textbook, andor your lab noses e orgänelle that you would espect to be most abundant in each of the following cells. a. A cell that produces an abundance of steroid hormones smooth endoplasmic reticulum: ribosome, rough endoplasmic reticulum b. A cell that synthesizes and secretes proteins Golgi apparatus: peroxisome, lysosome c. A cell that exhibits a high rate of metabolic activity Golgi apparatus; centriole; mitochondrion d. A cell that detoxifies alcohol peroxisome: rough endoplasmie reticulum; lysosome 2. Fall in the blanks as you deseribe how a pancreatic B-cell produces and secretes insulin. Insulin, a protein, is produced by ribosomes attached to the The insulin is then packaged by the Secretory vesicles pinch off, and the protein is released from the cell via a process called 3. In Lab Activity 3, the dialysis tubing containing 0.9% NaCl represented a "nonnal cel l' and the dialysis tubing containing 20% NaCl represented a "defective cell" Each of these placed in a 09 % Naci solution. Circle the correct term to describe the tonicity of the compared to the solution in which each was placed a. The "normal cell" was ells (hypertonic, isotonic, hypotonic) compared to the solation in which it was placed the solution in which it was placed b. The"defective cell., was (hypertonic, isotonic, hypotonic) compared to - 4. Complete the following tables to compare and contrast cell types Characteristics unique to a cardiac muscle fiber Characteristics common to both a cardiac muscle fiber and an erythrocyte Characteristics unique to an erythrocyt ns? lon Characteristics unique to a neuron Characteristics common to both a neuron and a sperm cell Characteristics unique to a sperm cell ment of 82 UNIT 5 I The Cell rogen, o

Explanation / Answer

1) a. smooth endoplasmic reticulum

b. Golgi apparatus

c. Mitochondria

d. peroxisome

2) Insulin produced by ribosome attached to the Endoplasmic reticulum.

The insulin is then packaged by golgi apparatus.

Secretory vesicles pinches off, and the protein is released from cell via a process is called exocytosis.

3) a. The normal cell was isotonic compared to solution in which it was placed.

b. The defective cell was hypertonic compared to the solution in which it was placed.

4)

1) Sperm cell transmit genetic material which is in the nucleus of its head to the offspring by penetrating into the ovum, and it can swim through its long tail.

2) Neck of sperm cell contains mitochondria which generates energy to swim the sperm.

1)Both sperm cell and neuron has nucleus in head of sperm cell and in soma region of neuron respectively.

2) neuron and sperm cell has long tail.

characteristic unique to cardiac muscle fiber characteristic common to both erythrocyte and cardiac muscle fiber characteristic unique to erythrocyte It has characteristic similar both to smooth and skeletal muscle tissue and contain large amount of pigment called myoglobin that transfers oxygen from blood to muscle cells Both have the pigment protein that has the capacity of oxygen. Erythrocyte contain a pigment protein called hemoglobin carries oxygen.
