TEMPURATURE:
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.
pH:
Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
DIFFERENT SUBSTRATES:
Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

Explanation:
How does the spread of an airborne pathogen compare to the spread of foodborne and person-to-person pathogens
Answer:
You must come in contact with the infected air. It spreads slower, and more than one person is usually affected at the same time.
Explanation:
contrast cellular respiration and fermentation and explain which process is more efficient. why do your body's cells use fermentation during intense exercise?
Answer:
Cellular respiration produces 38Atp while fermentation produces 2 Atp, that being said Cellular respiration is more efficient than fermentation in the generation of ATP.
Explanation:
in fermentation, glucose reacts in the absence of oxygen to produce ATP. Cellular respiration is the more efficient process because it produces much more ATP from each glucose molecule than does fermentation. the body's cells use fermentation during intense exercise because their oxygen supply is limited

Which organisms inhaled CO2 and exhaled 02 to 100s of millions of years, increasing the amount of O2 in the atmosphere?
Answer:
Plants
Explanation:
Plants 'inhale' CO2 and 'exhale' O2.
