Biology Unit 5
Enzymes, catalysts, energy (etc)
Question | Answer |
---|---|
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 |
