Biology Macromolecules and Enzymes Quiz

Johnny is doing a snatch at the gym as a regular exercise. Today he decides to increase the weight load by 25lbs on each side. He jokes with his friends that he will be sore the next couple of days. When he leaves the gym he drinks a protein supplement shake that his nutritionist suggested. Why does Johnny drink the protein supplement after a workout?

• There are many carbohydrates in a protein shake that will provide him with everyday energy so he will not be tired.

• There are many proteins and/or amino acids that muscles are primarily composed of and this will help repair his muscles so he will be less sore the next day

• There are many enzymes in his protein shake that will help speed up the chemical reactions to recover quicker so that he will be sore for less time.

• There are nutrients in a protein shake to replace his meals because he will not feel like eating a solid meal after a workout and will want something to help him recover without getting an upset stomach.

Acelya is practicing box jumps at the gym to help her train for a mud and obstacle race. Her trainer told her to do 5 jumps 5 then rest for 1 minute. Then her trainer tells her to do that exercise 4 more times. After Acelya did her 5 sets of 5 jumps she realized that it wasn't that bad when she took the one minute breaks. What type of macromolecule was she primarily using for energy?

• Carbohydrates because they give off energy for moderate lengths of time doing moderate exercises

• Fats because they are long term energy storage

• Nucleic Acids because her ability to do certain exercises are based on her genetic coding

• proteins because they provide short bursts of energy and can replenish themselves relatively quickly as well.

Limon Sky was having a difficult time focusing in school so she started to exercise to relieve her stress. She enjoyed the first week with her trainer but noticed she was starting to feel tired and wanted to workout but had low energy levels. Her trainer suggested an amino acid drink before working out and a protein and enzyme drink after her workout. Why would the trainer recommend this combination of supplements?

• the amino acids will give her immediate energy before her workout because they are the simple forms of proteins and do not need to be broken down. The post workout drink has enzymes and larger proteins to help repair her muscles at a moderate pace so that she doesn't get sore and feel very tired after her workout.

• the amino acids will give her long slow energy throughout her workout so she can workout longer. The post workout drink has enzymes and larger proteins to help repair her muscles at a moderate pace so that she doesn't get sore and feel very tired after her workout.

• the supplements will not help her feel more energized but they will help her muscles recover faster so she will not be sore and want to keep exercising everyday.

• the supplements will help her to feel more energized because amino acids and proteins are the same thing just different sizes. The enzymes are in the drink to make the energy release quicker.

Mason got a job working at a nutrition store and noticed there was a product that claimed to increase muscle size by 30% within 8 weeks of using the product! The supplement compared their amino acid leucine to a carbohydrate placebo. What is the error with this comparison?

• The claim that you can increase your muscle size by drinking a supplement is false.

• The claim that you can increase muscle size in only 8 weeks is outrageous

• The product is found in a nutrition store so there cannot be any errors in what is being sold.

• The claim compares the effectiveness of a protein to a carbohydrate when trying to improve muscle growth.

This is an image of adipose tissue. Humans rely on the storage of lipids within adipose tissue for long term energy storage. Alara is taking her German Shepherd on a one mile run daily and has been told by doctors that she and her dog need to balance healthy sources of fat in their diet. Where can Alara find a healthy source of fat for both she and her German Shepherd?

• nuts, ice cream, steak, yogurt, bagels

• nuts, seeds, fish, cheese, pastries

• avocado, nut butter, fish, olives, eggs

• fish, eggs, milk, honey buns, dark chocolate
