JA - Edpuzzle Quiz 2

| Question | Answer |
|---|---|
| Catalase is an enzyme that breaks down | hydrogen peroxide (H2O2) |
| Hydrogen peroxide breaks down to produce | water and oxygen |
| What fits into the active site of an enzyme? | substrate |
| How does the substrate fit into the active site of an enzyme? | in a one-to-one relationship -- like a key fits into a lock |
| After a substrate enters the active site of an enzyme, bonds will break and new bonds will form to produce | product(s) |
| Some enzymes require cofactors and/or coenzymes in order for the enzyme | to be activated |
| What type of inhibitor stops the function of an enzyme by fitting into the active site? | competitive inhibitor |
| An increase in the amount of enzyme in a reaction will | increase the rate of the reaction |
| why would the rate of the enzyme reaction, that is receiving increasing amounts of enzymes, eventually level off? | the reaction would run out of substrate |
| As we increase the temperature in an enzyme reaction, why does the rate of the reaction increase and then decrease? | at high temperatures, the enzyme will become denatured |
| What is the first step in drawing a graph? | Draw the x-axis and the y-axis |
| What type of graphs are covered in this tutorial? | line |
| If time is a variable, what type of variable will it be? | independent |
| Which axis is the independent variable placed on? | x |
| In addition to the variable, what must be included on the axis label? | units |
| The rate in a graph is the variable on the y-axis over (divided by) | time |
| Which variable is the manipulated variable or the variable that you directly control? | the independent variable on the x-axis |
| The resulting variable (or the data that you collect during the lab) is the | dependent variable on the y-axis |
| Which variable is the manipulated variable in the example to the left? | caffeine (mg/mL) |
| Which of the following is a second reasonable title for the daphnia experiment? | Heart beats per minute dependent on quantity of caffeine intake. |
| What is the purpose of the Enzyme Activity Lab? | to measure the rate of the enzyme action |
| What does hydrogen peroxide break in to? | water and oxygen gas |
| Instead of using chads, we will place the liver and hydrogen peroxide in a bag. If the enzyme is active, the bag will start to expand. What is the major factor that will cause the bag to expand? | oxygen gas |
| When will enzyme concentration no longer increase the rate of the reaction? | when there are more enzymes than needed for the amount of substrates |
| Remember the graphing tutorial, Part 1. Which variable in the graph shown is the independent variable? | concentration (g/L) |
| What is the purpose of an axis break? | it allows you start numbering an axis at a number beyond zero |
| When plotting points, you should use one set of numbers. One number refers to the x-axis and the second number | refers to the y-axis |
| A curved line should be drawn with | a smooth curve |
| A line of best fit is a straight line or a curve that shows the | average line between points |
| A point on an error bar shows the | average of several numbers |
| Does the line of best fit run through all of the error bars? | yes |
| What is the metabolism | the sum of all of the chemical reactions in our bodies |
| Which of the following is NOT one of the three major uses of free energy | release waste |
| In organisms, a constant supply of energy is needed to maintain | order |
| The second law of thermodynamics states that | conversion of energy increases the entropy of the universe |
| The folding in of the membrane in the eye allows organisms to sense | motion |
| The process of glycolysis starts with glucose and ends with | pyruvate |
| Can any sugar besides glucose be broken down during glycolysis? | Yes, different sugars (galactose, fructose, etc.) can go through glycolysis, but they enter the process at different points. |
| Which of the following animals do you predict to have the higher metabolism? | rabbit |
| Which of he following requires extra energy (beyond the norm) | reproduce |
| The collapse of Easter Island was due to | a decrease in free energy |
| Free energy can also be described as | available energy |
| Enthalpy (H) is also known as | Total energy |
| In Biology, which of the following is a source of energy? | energy stored in chemical bonds |
| Which type of room has more entropy (S)? | messy room |
| Under what conditions would a bomb be more likely to explode? | high temperature (T) |
| What type of △G results in a spontaneous reaction? Note: a spontaneous reaction is a reaction that will react without the need for additional energy. | -△G |
| Reactions that are spontaneous are | exergonic (energy releasing) Note: exothermic is a similar term |
| Cellular Respiration has a | -△G and is spontaneous |
| Where does photosynthesis get the activation energy needed for the reaction to take place? | the sun |
| Photosynthesis has a | +△G |
| Do all living organsims use ATP? | yes |
| How many phosphates does ATP have? | 3 |
| If water is added to ATP, it will go through hydrolysis. The ATP will break into one phosphate (Pi) and _________. | ADP |
| Which of the following is similar to a fully charged battery? | ATP |
| What process uses energy to reattach a phosphate (Pi) to ADP to produce ATP? | dehydration synthesis |
| What reaction(s) involve the production of ATP? | cellular respiration and photosynthesis |
| One use of ATP is fueling sodium potassium pumps which are working in your | neurons |
| Muscle contraction is going to occur by using the ______ from ATP. | phosphate |
| ATP was used by LUCA. What is LUCA? | Last Universal Common Ancestor |
| Which of the following is NOT found in all living organisms? | mitochondria |
| Where on the plant will the chads (I call them leaf disks) come from? | leaves |
| What is the purpose of using a syringe to pull the gasses out of the leaf disks? | they will sink to the bottom of a beaker |
| How will we add carbon dioxide to the beaker? | baking soda (sodium bicarbonate) |
| What is going to cause the leaf disks to float to the top | oxygen production |
| What is being tested in this lab? | the rate of photosynthesis |
| Which of the following can make their own food? | autotrophs |
| Which process uses chemicals to make food | chemosynthesis |
| Which of the following do plants complete? | photosynthesis and respiration |
| The purpose of photosynthesis is to | store energy in the bonds of the glucose molecule |
| In photosynthesis, where do the electrons come from that travel along the electron transport chain? | water |
| In the light reactions of photosynthesis, where is the energy from the light stored? | NADPH and ATP |
| Where did the oxygen in the atmosphere (that began increasing significantly 2.1 billion years ago) come from? | photosynthesis |
| Respiration is an ____________ reaction since it releases ATP. | exergonic |
| After glycolysis, the Krebs Cycle stores energy in | NADH and FADH2 |
| In Respiration, where do the electrons end up? | they join with oxygen (and protons) to make water |
