Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes would you expect to be key in the production of yogurt?
a. Photosynthesis
b. Lactic acid fermentation
c. Krebs cycle
d. Alcoholic fermentation
Answer:
b. Lactic acid fermentation
Explanation:
Lactic acid fermentation occurs when pyruvate formed by glycolysis is reduced into lactate under the anaerobic conditions. The NADH serves as an electron donor for the reduction of pyruvate into lactic acid. Lactic acid bacteria are the anaerobic bacteria that ferment the milk sugar lactose into lactic acid. This converts the milk into yogurt. <em>Lactobacillus, Streptococcus salivarius</em>, etc. are mostly responsible for the conversion of milk into yogurt.
A. the temperature at which the water vapor will condense
Answer:
Depends on temperature
Explanation:
If the volume of a container is increased, so does the temperature.
If the volume of a container is decreased, so does the temperature.
Endemism
Endemism is the state of a species being native to a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere.
Explanation:
Endemic species are those that are found in just one region and nowhere else in the world. For example, kangaroos are originally endemic to Australia and are found nowhere else in the world. ... The Tasmanian Tiger is one such animal that was endemic to Australia, Tasmania and New Guinea. But now, it is extinct.
Answer:
The correct answer is - Protein molecule.
Explanation:
The cell membrane is the outer membrane of the cell that differentiates the external environment from the internal components of the cell. The cell membrane is made up of two major components that are lipids and proteins.
Proteins are present as channels and in the form of membrane proteins in between the lipid bilayer. Protein is the molecule that denatured or destroyed at high temperatures such as 70 degrees.
