Enzymes is one of the science materials you can find on Amoeba Sisters. For this material, you will need to answer some questions related to Enzymes. You definitely need to describe the effects that enzymes can have on substrates.
If you are accidentally looking for the Amoeba Sisters Video Recap Enzyme answers, you can dive into our post, since this post will show you the answers to the Amoeba Sisters Video Recap Enzyme. Let’s dive into our post to find these answers!
Amoeba Sisters Video Recap: Enzymes
Question:
- In the box below, please illustrate an enzyme and substrate. Label the following keywords in your illustration: enzyme, substrate, and active site.
- Enzymes are typically which type of biomolecule? Protein
- Describe the effects that enzymes can have on substrates. Held to enzymes using weak bonds they can build or break down enzymes.
In order to function efficiently, enzymes need to be at an ideal pH and temperature. Different enzymes have different ideal pH and temperature conditions. If the pH or temperature is extreme for a particular enzyme, it can even denature an enzyme, which can prevent it from binding and acting on its substrate. For the following two scenarios, name the variable (temperature or pH) that is affecting the function of the enzyme.
A)ATP is produced by cellular respiration in your human body cells. There are a variety of enzymes that work to produce ATP, but one of those enzymes is called phosphofructokinase-1. This enzyme is sensitive to blood acidity. Blood can become more acidic if a patient is in respiratory distress.
- Variable affecting enzyme function: pH
A)A popular lab that can be performed by students is to test the reaction rate of catalase enzyme when it acts on the substrate hydrogen peroxide. Catalase has the ability to break down hydrogen peroxide. Catalase can be found in beef liver from the grocery store! However, if the beef liver is boiled first, the catalase will not be able to break down hydrogen peroxide.
- Variable affecting enzyme function: temp
Real Life Enzyme Scenarios
Please fill in the chart for every real-life scenario listed below. Some boxes have been filled in for you!
| Scenario | Identify Enzyme: | Identify
Substrate |
Illustrate the Scenario (label enzyme and substrate in illustration): | Describe the relationship between the substrate and enzyme in the scenario
|
| Lactase is an enzyme that breaks down a sugar found in dairy products known as lactose. Some people are lactose intolerant, and this can be due to not having enough lactase production. People who are lactose intolerant may not feel well after eating foods containing lactose.
|
6. | Lactose | 7. | 8. The lactase production is not enough resulting in the person feeling sick when consuming dairy. |
| An enzyme called glucocerebrosidase breaks down a glycolipid in the body known as glucocerebroside. However, in a genetic disease known as Gaucher’s disease, the body does not produce enough glucocerebrosidase. Therefore glucocerebroside can build up in the body and this can cause serious side effects such as anemia and swelling of the liver and spleen.
|
9. Glucocerebroside | 10. glycolipid | 11. | 12. The body does not produce enough glucocerebroside and can swell the river |
| Pancreatitis is an inflammation of the pancreas which can damage pancreatic tissue. The pancreas produces digestive enzymes such as amylase and lipase. These enzymes assist in breaking down certain food biomolecules. In this disorder, enzyme production from pancreatic tissue may be stopped.
|
13. Amylase lipase | 14. pancreatitis | 15. | Since the pancreatic tissue can be damaged in this disorder, the production of the enzymes in this tissue (amylase and lipase) may be disrupted as well. This would affect the ability to break down certain types of food biomolecules (substrate). |
Get to Know about Amoeba Sisters
Amoeba Sisters is a YouTube Channel that teaches science showing two amoebas. This channel was created by sisters Sarina Peterson and Brianna Rapini in July 2013. They specialize in teaching biology concepts at the high school level by using illustrated cartoons.
Sarina Peterson is a former program analyst in a large Texas public school district who is known as a self-taught cartoonist. Brianna Rapini is a former high school biology teacher who worked in three different Texas public school districts for a total of 12 years.
Based on their stories, the Amoeba Sisters channel was created as a way to create memorable and short biology videos which could be used in lieu of lengthy lectures so that more time would be available for class discussion, student creation and labs.
The Amoeba Sisters YouTube Channel is intended for high school biology (as Pinky is a former high school biology teacher). In fact, a public survey of more than 26,000 viewers on their YouTube community tab showed about 37% of the responding audience as college/university students when many of the concepts are taught in introductory biology at the college level.
Amoeba Sisters actually create science YouTube videos, comics, GIFs and resources. Of course, you cannot find all of those creations on or linked to this website. As we’ve mentioned, they are two sisters from Texas.
Petunia is the creator of the GIFs and comics. To create the videos, she times the comics to Pinky’s audio. She has no formal training in art, but she has practiced a lot. You definitely can see the progression of her art on the milestones page. Well, she has a better sense of humor than her sister counterpart.
Pinky works to write the scripts, designs resources, records her voice to complement the videos. Pinky has a biology degree, a passion for using EdTech to involve students as creators and a public high school science teaching background.
Amoeba Sisters focus on their interests so much that Petunia prefers to practice her love of drawing, while Pinky prefers to practice her love of teaching. If they switched roles, they would have to subject everyone to iguanas and silkie bantam chickens that are illustrated by Pinky.
