Photosynthesis and Cellular Respiration
100
Enzymes are named after the substrate they react with - replacing the "ose" with "ase". This is the enzyme that breaks down Lactose.
What is Lactase?
100
The energy needed to start a reaction is called this.
What is activation energy?
100
Enzymes _________ reactions in the cells.
What is speed up?
100
This is the term used when the enzyme is actively operating on the substrate causing the reaction.
What is an enzyme-substrate complex?
100

This is where the light dependent reaction occurs during photosynthesis.

What is the chloroplast?

200
True or False: Enzymes are used up during their reaction.
What is False? Enzymes do not get used up. They are free to react again and again. This is why they are only need in the body in small amounts.
200
True or False: All reactions require the same amount of ENERGY to get started.
What is false?
200

Enzymes are this type of biomolecule.

What is proteins?

200
This is what the Enzyme acts upon.
What is a substrate?
200

True or false: The reactants of cellular respiration are 6 CO2 and 6 H2O.

What is False?

300
Explain what is meant by "Enzymes are substrate specific"
What is they only react with certain substrates that fit into the active site. Think Lock and Key!
300
This protein will reduce the activation energy.
What is an enzyme?
300
Enzymes lowers activation energy & speeds something up. Another word for this is a ____________.
What is catalyst?
300
Where the specific substrate fits in the enzyme.
What is an active site?
300

This is the formula for photosynthesis:

What is Light Energy + 6 CO2 +6 H2O -> C6H12O6 + 6 O2?

400
Describe the Lock and Key hypothesis using the terms substrate and enzyme. Which is the lock, which is the key?
What is Enzymes only react with certain substrates that match their shape correctly. Enzymes are the lock, substrates are the key.
400
An enzyme will ____________ the amount of activation energy required.
What is reduce?
400
Enzymes are substrate specific, this means?
What is Enzymes only react with specific substrates that fit into the active site (Lock and key)
400
The “new” substance created during reaction.
What is a product?
400

These processes are mirror images of each other, with the exception of type of energy used. 

What is photosynthesis and cellular respiration?

500

Describe the differences between a synthesis or deydration reaction and a hydrolysis reaction.

What is: Dehydration or synthesis is a building up reaction (2 substrates join into one) hydrolysis is a breaking down reaction involving water (1 substrate breaks into two)?

500
Activation energy is the energy needed to start a ________.
What is reaction?
500
True or false: For each reaction, there is a specific enzyme.
What is true?
500
After the reaction, the enzyme is _________.
What is reusable?
500

The formula for Cellular Respiration is _______________________. 

What is C6H12O6 + 6 O2  -> 6 CO2 + 6 H2O + ATP?
