Catalase is an enzyme which is present in every living organism that is exposed to oxygen. Catalase's activity is affected by temperature, pH and the concentration of substrate. In catalase's case, the substrate is the hydrogen peroxide. If any of these factors change, the effectiveness of the catalase to catalyze the decomposition of hydrogen peroxide will deteriorate. If the temperature and pH change, the shape of the enzyme will change as well. This denaturation of the enzyme will obstruct the hydrogen peroxide molecules to fit in the catalase's active site.
The correct answer is A since i can't see what is under it
Answer:
1. Use less cars travel way less with them if youan use a bike or walk to try stop too much CO2 being produced
2. Use less papaer or recyle trees are being cut down for them wich break down habittats and prevents filtrating CO2
3.RECYLE recylimg is something everyone can do it helps stop polution, rubish being frown in the seas oceans and animals eating them
Answer:
B. Explore uses of more plentiful minerals
Answer:
Isometric
Explanation:
Isometric contraction may be defined as the type of contraction that produces the muscle tension. No change in the angle of the skeletal joint is noticed in the isometric contraction.
The sarcomere shortens during the muscle contraction this causes the increase in the muscle tension of the muscle. The length of the muscle do not change in the isometric contraction. The isometric contraction is important for maintaining posture.
Thus, the correct answer is isometric contraction.
