A protease enzyme is found in the stomachs of humans. it catalyses the breakdown of long chains of amino acids(proteins) into individual amino amino acid molecules. a)suggest the optimum temperature for the activity of this protease enzyme

b)the stomach contains hydrochloric acid. suggest the optimum pH for the activity of this protease enzyme

c)Explain why the rate of an enzyme_controlled reaction is relatively slow at low temperatures.

d)expalin why the rate of the reaction slows down above the enzyme's optimum temperature.​

The oxidizing agent our bodies use to obtain energy from food is oxygen (from the air). if you breathe 15 times a minute (at rest), taking in and exhaling 0.5 l of air with each breath, what volume of air do you breathe each day? air is 21% oxygen by volume. what volume of oxygen do you breathe each day?

Any sound above what db can cause hearing loss in human beings

Use this dichotomous key for insect identification to identify the insect shown. 1. a. insect has one pair of wings. order diptera b. insect has two pairs of wings. go to #2 2. a. front wings thicker in texture than hind wings go to #3. b. front and hind wings are same texture throughout. go to #4 3. a. front wings are short order dermaptera b. front wings cover entire abdomen order coleoptera 4. a. wings with scale on all parts of their area. order lepidoptera b. wings without scales go to #5. 5. a. hind wings smaller than front wings. order ephemeroptera b. front and hind wings nearly equal in size. order odonata the insect pictured is in the order diptera. ephemeroptera. coleoptera. odonata.
