1. what limits do common names have?
they depend on geography.
they often use multiple words.
they are non-descriptive of the organism.
they are descriptive of the organism.
they can be in different languages.
none of the above

Explanation:

Common names are local names that are given to organisms. These names are widely and locally accepted even within scientific bodies in order to avoid the rigors of having to use latin names of organisms.

Some of the limits of using common names are:

1. They can depend on geography: some common names are restricted in their use based on their acceptance by set of people. In some other climes, they might not be accepted. This is one big limitation in using common names.

2. They often use multiple words: within a particular area, an organism can be called different names. This is yet another big limitation of common names.

3. They are can be descriptive or non-descriptive of the organism: some common names are descriptive and they can easily tell us about an organism. Others might not even relate to to the organism at all.

4. They can be in different languages: Most languages have a common name for all organisms. This pose a serious scientific barrier when studying such species.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?
