Answer: Enzymes lower the activation energy found in food molecules
Explanation:
Food substances like yam, potatoes, egg etc are all made of chemical elements bounded to one another by chemical bonds such as hydrogen bonds, covalent bonds etc
During digestion, these bonds must be broken for carbohydrates to yield glucose, protein to yield amino acids.
Hence, added enzymes lowers the strength of this bonds i.e activation energy, by placing them into their active sites, which is equipped to cleave specific bonds
Thus, digestive reactions are quicker in the presence of enzymes than otherwise.
Robert Steve and James are three new organisms ( lizard species ) Steve can breath under water he has scaly moist lizard skin a long strong tail and very sharp claws weighs 20 pounds and is 6ft long Steve prefers to eat small fish.
Robert can't breath under water has scaly dry lizard skin very sharp teeth and is very poisonous he has night vision weighs 5 pounds and is 2 ft long he mainly eats small bugs like lies and wasps.
James on the other hand is completely different he has is 10 feet long weighs 180pounds can run 5 miles per hour has powerful jaws that can break bones he has razor sharp teeth and claws and poisonous spit he has a smell radius of 15 miles and is a very heavy set he also prefers to eat big land animals like deer he's a Carnavor.
all of these Organisms are in a similar species (Lizard) and have similar characteristics ( Like scaly lizard skin and sharp claws) but they all have different traits and abilities.
I Hope this helped you.
I think it's axial precession \
Hope it helps!
