Enzymes
Enzymes lower what in a chemical reaction? What does that mean?
activation energy; lower the amount of energy needed to start a reaction
Where is all the energy stored?
The phosphate bond between the second and third phosphate
What is the purpose of Cellular Respiration?
important so that plants and animals can convert food energy (sugar) into ATP
Fermentation indirectly makes ______ net ATP by allowing _________ to continue?
2; Glycolysis
Photosynthesis makes the product __________ in order for ______________ to start.
glucose; Cellular Respiration/Glycolysis
The whole reason we have enzymes in our body is to help in what processes?
chemical reactions
In organisms, _______ is converted into ATP?
food
What is the starting point for the ETC? i.e. what does it need to start AND why?
FADH2 and NADH; need electrons to start
What electron carrier is needed for Glycolysis to start? What electron carrier is made in Glycolysis?
1. NAD+
2. NADH
Where does the Hydrogen come from that ends up making sugar?
water splitting
Enzymes and their substrates are sometimes compared to what model?
Lock & Key
Accurately (shapes included) draw and label an ATP molecule on the board including bonds
Adenine (two molecules, six sides)
Ribose (5 sides)
Three Phosphate bonds
We say Glycolysis makes a *net of 2 ATP. How much does it actually make and what happens to the other 2 ATP?
4; 2 ATP are used to split the glucose in half
Where is NADH headed when it hits a roadblock of no oxygen and has to pivot to fermentation?
Electron Transport Chain
What are the three things made in the Light- Dependent Reaction?
1. ATP
2. NADPH
3. Oxygen
What is a chemical reaction called that uses up energy? What is a chemical reaction called that releases energy?
You must know how to spell them... choose someone to come write the answer(s) on the board
1. Endergonic
2. Exergonic
How many carbons does Ribose have?
5
What happens to Pyruvic Acid in the Krebs Cycle?
Oxidizes to become carbon dioxide which is released into the atmosphere
In fermentation NADH is recycled to NAD+ by giving electrons back to who?
Pyruvic Acid
What are the three things made in the Light Independent Reaction?
1. ADP
2. NADP+
3. Glucose
Lactase is the name of an enzyme in our body. What organ does this enzyme reside in AND what is the name of its' substrate?
small intestine; Lactose
Why don't phosphates naturally want to stay attached to each other?
They are all negatively charged
Accurately write the chemical (not word) equation for cellular respiration on the board
602 + C6H1206 --> 6CO2 + 6H20 + energy
Wrote both equations for alcoholic fermentation and lactic acid fermentation on the board. (in word form)
Pyruvic acid + NADH ---> alcohol + CO2 + NAD+
Pyruvic acid + NADH ---> lactic acid + NAD+
