Quiz Questions 1
______________ acts as the body’s primary storage form of glucose, which is essential for fueling muscles and maintaining blood sugar levels during exercise.
Glycogen
________ glycogen helps maintain blood glucose levels, providing energy to the body during long periods of physical activity and fasting.
Liver
ATP, which contains __ phosphate groups, ADP contains only __.
3,2
What phase of Cellular Respiration does this fall under?
High-energy electrons from NADH and FADH2 (produced in the Krebs cycle) are transferred through protein complexes in the inner mitochondrial membrane. This creates a proton gradient across the membrane, which is used to generate ATP via ATP synthase. Oxygen is the final electron acceptor, combining with electrons and protons to form water.
ETC
Before Miley Cyrus recorded "Wrecking Ball," it was offered to which singer?
Beyonce
The cellular respiration process occurs in _____ main stages
3
__________ is the immediate source of energy for muscle contraction, and glycogen provides a rapid source of glucose to regenerate this
ATP
Glycolysis (Anaerobic Phase); Occurs in the ____________ of the cell.
cytoplasm
Which nutrient is the main source of energy?
Carbs
Which singer performed at the 2015 Super Bowl halftime show?
Katy Perry
What are the stages in the cellular respiration process?
Glycolysis (Anaerobic Phase), Krebs Cycle (Citric Acid Cycle, Aerobic Phase), Electron Transport Chain (ETC)
What is this process called? The glycogen stored in muscles is broken down into glucose molecules to produce adenosine triphosphate (ATP), the energy currency used by muscles to contract.
Glycogenolysis
Krebs Cycle (Citric Acid Cycle, Aerobic Phase); Takes place in the _____________________ of the cell.
mitochondria
In humans, the majority of glucose is stored in the _________.
Whitney Houston famously covered “I Will Always Love You”—who sang the original?
Dolly
_____________ is the primary energy source for all cellular activities, including muscle contraction.
ATP
___________ occurs when ATP demand exceeds the body’s ability to produce it, impairing muscle function and performance.
Fatigue
Different types of exercise rely on varying contributions from aerobic and anaerobic systems. For example, during a sprint, ____________ glycolysis dominates, whereas, during a marathon, ______________ respiration is the primary energy source.
anerobic; aerobic
When participating in very mild aerobic activities, which of the following will lead to fatigue in very prolonged bouts?
A. Diminishing carbohydrate levels.
B. Low blood-sugar levels.
C. Low stores of fat.
D. All of these answers will lead to fatigue.
All of these answers will lead to fatigue.
Who won country album of the year this year at the Grammy's?
Beyonce - Cowboy Carter
_______ glycogen is the primary energy source used during exercise, particularly during activities involving movement, like running or weightlifting.
Muscle
Write the ATP Hydrolysis reaction
ATP→ADP+Pi+Energy
T or F: The Krebs cycle is central to understanding how the body produces energy during anerobic exercise.
False
Which energy system would predominate in an all-out, high-intensity, 100-meter dash in track?
ATP-PC (phosphagen)
Who will win the super bowl 2025?
