Answer:
Anaerobic respiration or fermentation
Explanation:
The metabolic pathway shown in the question is the summary of anaerobic respiration (fermentation) during which pyruvate is converted to acetaldehyde, followed by the formation of alcohol (ethanol), along with the release of NADH and NAD molecules. This mechanism occurs in the absence of oxygen and is thus used by organisms to generate energy (ATP) molecules.
Answer:
Explanation:
If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon. Tanner further explained that a scientific theory is the framework for observations and facts.
Answer:
ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles →cell surface (exocytosis) (see Figure 17-13). Small transport vesicles bud off from the ER and fuse to form the cis-Golgi reticulum.
