Sugar Metabolism
Title: The effectiveness of glucose and fructose metabolism in individuals of resting and exercising observed through blood glucose concentration.
Aim:
To study the mechanisms of the body involved in absorbing and metabolizing sugar in the form of glucose and fructose and examine the effect of exercise on the rate of removal of glucose from the bloodstream.
Introduction:
The blood glucose concentration in the blood is interceded by the human body via negative feedback mechanism to maintain homeostasis of the body. Free glucose can be produced from fat, gluconeogenesis from proteins and glycogenolysis in liver and glucose is stored as glycogen in the muscle tissues. The human body intends to maintain a stable glucose concentration
Meanwhile, fructose+ rest and glucose ‘sip and spit’ subjects only had slight increase in blood glucose concentration. The highest increase in blood glucose concentration is in glucose+ rest subject followed by glucose and exercise subject. The peak value for glucose+ rest treatment subject occurs at 60 mins time interval with concentration of 9.6mM and the peak value for glucose and exercise treatment subject occurs between 20 and 40 mins time interval with concentration of 7mM. After 60 mins, the blood glucose concentration for both glucose+ rest and glucose and exercise treatment subjects starts to
The glucose + rest treated subject had the highest change in blood glucose level, followed by fructose and rest subject. The glucose ‘sip and spit’ had the second lowest change in blood glucose concentration and glucose and exercise had the lowest change in blood glucose concentration and the entire treatment group had SEM bars.
Discussion:
Based on the results and BMI of all the subjects, there is no correlation between BMI and blood glucose concentration. This can be seen in Figure 1, where the R2 value obtained from the regression line of the scatter plot was low, with a value of 0.089. Fatty acid can be synthesized from simple carbohydrates like glucose; however other factors may be involved in inducing an increase on its own (Nelson & Cox, 2004). For subjects in category 1, where they had to drink glucose water had an increase in blood glucose concentration until the 60th minute. Blood glucose concentration decreased when it was measured at 90th and 120th minute, as shown in Figure 2. This shows that glucose had been metabolized and broken down to be
