Biology Unit 5

Enzymes, catalysts, energy (etc)

What are enzymes made of? Amino Acids
4 characteristics of enzymes 1. Speed up reactions 2.can be recycled 3.very specific to different reactions 4.Lower amt of energy required
Why can enzymes be recycled? enzymes are unaffected by the reaction and then it gets let go and used for another reaction!
How do enzymes lower the energy required for a chemical reaction? They skip all the bouncing around and just grab two & collide together.
What is chemical energy? Stored in bonds between atoms in food molecules.
Primary source of energy in our cells Heat energy
How do we use the chemical energy in ATP? Metabolism Maintain homeostasis
ATP= Adenosine triphosphate
3 bonds = ATP
2 bonds= adenosine diphosphate
1 bond= adenosine monophosphate
3 groups that photosynthesize Algae Bacteria Plants
Who discovered Cells? Robert Hooke
What does cell theory state? All organisms made of cells Cells are alive & basic unit of organisms Cells come from other cells
3 scientists and what they said: 1. Theodore Schwann- All animals are made of cells 2.Matthias Jakob Shleiden- all plants are made of cells 3. Rudolf Vierchow- cells came from other cells
