Tanks in Steps

1. (Step 1): CNS is using blood glucose for energy (happening 24/7).

2. What process(es) are occurring and the enzymes facilitating the process(es) ?

• Glycogenolysis. (Glycogen Phosphorylase & Phosphatase)

• Glycolysis.

  (PFK)

• Gluconeogenesis.

  (no enzyme)

• Lipolysis.

  (Lipase)

1. (Step 2): We begin to exercise at high intensity. Muscles are using MG for most of their fuel (ATP) needs, 25% FATS, 5-10 % protein. Muscles is also using a bit of BG for fuel. What are the processes and enzymes that get elevated with the onset of exercise?

   
   

• Lipolysis

  (Lipase)

• Proteolysis

  (No enzyme)

• Glycogenolysis

  (Glycogen Phosphorylase)

• Glycolysis

  (PFK)

(Step 3): Blood Glucose levels drop. That hormone that is released in response to this condition is

1. (Step 4): We decrease blood glucose usage by the muscles to maintain available blood glucose for CNS

• True

• False

1. (Step 5:) Liver Glycogen (L.G) is broken down to release glucose to blood.

What process(es) are occurring and the enzymes facilitating the process(es) ?

• Gluconeogenesis

  (no enzyme)

• Glycogenolysis

  (Glycogen Phosphorylase)

• Glycogenolysis

  (Glycogen Phosphorylase and Phosphatase)

• Glycogenesis

  (glycogen synthesis)

1. (Step 6): After 90 minutes to 2 hours, what CHO stores are depleted significantly?

• Muscle Glycogen (M.G)

• Liver Glycogen (L.G)

• Blood Glucose (B.G)

• Fatty Acids

(Step 7): Muscles increase BG usage once again since we are out of fuel in our tanks. What process(es) are occurring and the enzymes facilitating the process(es) ?

• Gluconeogenesis

  (no enzyme)

• Glycolysis

  (PFK)

• Lipolysis

  (Lipase)

• Protein Synthesis

  (no enzyme)

(Step 8): Blood Glucose (B.G.) drop further

• True

• False

9. 9. If we are not eating additional carbohydrates, where and how are we creating new glucose and getting fuel to be broken down into energy?

• Lipolysis

  (60-80%)

• Proteolysis

  (20-40%)

• Gluconeogenesis

• Glycogenesis
