Question

1. the human body maintains a temperature of around 98.6 degrees at all every chemical reaction in the body. which of the following describes the statements? a. there is no connection between the two statements b. the body needs to be warm to prevent hypothermia c. the body is kept warm to prevent too much enzyme activity d. enzymes function best at a specific temperature 17. a fatty acid is unsaturated if it a. has double bonds and is liquid at room temperature b. has single bonds and is solid at room temperature 18. which of these is not a lipid a. oil b. fat c. polysaccharide d. wax

Explanation:

1. Enzymes have an optimal - temperature range for best function. The human body maintains a constant temperature around 98.6 degrees to ensure enzymes work efficiently.
2. Unsaturated fatty acids have double - bonds in their carbon - chain structure and are liquid at room temperature.
3. Lipids include fats, oils, and waxes. Polysaccharides are carbohydrates, not lipids.

Answer:

1. d. Enzymes function best at a specific temperature
2. a. Has double bonds and is liquid at room temperature
3. c. polysaccharide
