Measles
2. What microbe causes stomach ulcers (gastric
ulcers) Helicobacter pylori
3. What infectious class of organisms is known to be transmitted by pork
and stimulates production of eosinophils?
Helminthic
4. Which type of hypersensitivity involves only cell mediated
immunity? Type IV.
5. Know examples of signs and symptoms
Type 1- Anaphylactic, hives, wheal and erythema
Type 2- asthma, rhinitis, dermatitis and

12.Does glycolysis occur in the absence of oxygen? Is pyruvic acid, CO2 & H2O
end products of glycolysis? Does glycolysis occur during fermentation? Does
glycolysis reduce NAD?
, Glycolysis occurs when glucose and oxygen are supplied to the cells by the
bloodstream, and it takes place in the cell's cytoplasm. Glycolysis can also occur
without oxygen, a process called anaerobic respiration, or fermentation. When
glycolysis occurs without oxygen, cells make small amounts of ATP
Is pyruvic acid, CO2 & H2O end products
of glycolysis? Yes
Does glycolysis occur during fermentation?
. Glycolysis can also occur without oxygen, a process called anaerobic respiration,
or fermentation. When glycolysis occurs without oxygen, cells make small
amounts of ATP
Does glycolysis reduce NAD?
In the process of glycolysis, NAD+ is reduced to form NADH + H+. If NAD+ is
not present, glycolysis will not be able to continue. During aerobic respiration, the
NADH formed in glycolysis will be oxidized to reform NAD+ for use in glycolysis
again
