A. Mouth
B. Stomach
C. Small intestine
D. Large intestine - Answer-B. The stomach
The stomach is the first place in the digestive system in which proteinases are produced.

A. Cytotoxic T cell
B. Macrophage cell
C. Helper T cell

Which of the following structures within a human cell is responsible for recycling the materials no longer
functional or needed within the cell?
, A. Ribosome
B. Lysosome
C. Mitochondrion

Which of the following is the correct structure and function of the cell membrane?
A. A double glycoprotein structure with embedded lipid bodies provides shape and rigidity to the
cytoplasm.
B. A double layer of phosphate proteins with lipid channels allows molecules to pass from the inside to
the outside of the cells.
C. Nonpolar phosphate heads and polar lipid tails from a bilayer to control the transport of proteins.
D. A phospholipid bilayer with embedded proteins regulates molecules entering and leaving cytoplasms. -
Answer-D. A phospholipid bilayer with embedded proteins regulate molecules entering and leaving
cytoplasms.
The cell membrane consists of a phospholipid bilayer with polar phosphate heads, non polar lipid tails,
and embedded proteins, which permit the movement of molecules across the membrane.
which of the following chemical compounds prevents the lungs from collapsing?
A. Mucus

Which of the following appropriately completes the below statement?
"Unlike Skeletal muscle, cardiac muscle is highly resistant to lactate-meditated fatigue because cardiac
muscle"
A. Use aerobic respiration in mitchocondria for energy
B. Operates with electrical energy supplied bu the sinoatrial (SA) node.
C. Primarily metabolizes glucose using the fermentation pathway.
D. Does not need oxygen for the production of energy. - Answer-A. Use of aerobic respiration in
