andrey2020 [161]

Question: One way that researchers study the effects of trans fats on people's health is by setting up controlled experiments. For example, in an experimental feeding trial, participants agree to stick to specific diets that the researchers prescribe. In this case, the researchers might vary the proportions of saturated, unsaturated, and trans fats in the diet of each participant. Throughout the study, the health status of the participants is monitored closely.

Suppose that you are a researcher designing an experimental feeding trial. How would you set up your study and what limitations would you face?

Drag the labels onto the flow chart to identify the elements and limitations of your experimental design.

Explanation:

Hypothesis: Trans fat have found having negative effect on the cardiovascular effect.

Prediction : Eating more trans fats will have more risk of cardiovascular health problems.

Experiment: Feeding some people with a diet of higher trans fat and feeding others with a diet lower in trans fat.

Data collection: Blood samples are taken to measure the fat and cholesterol level in the two groups.

Practical limitations:* Is it possible to completely regulate people's diet?

* Are other life style factors affecting cardiovascular

health?

Ethical Limitation: Are we putting individuals health at risk?

The fourth reaction involving Gly-4 ( aldolase) is an especially important reaction in glycolysis. Why is this?

lapo4ka [179]

Glycolysis is the metabolic process of converting glucose into a pyruvate. It serves as a foundation for the two cellular respiration namely the aerobic and anaerobic respiration. It has four reactions namely, hexokinase, glucose-6 pshospahate isomerase, phosphofructokinase (PFK) and aldolase.

Aldolase or Glycolysis reaction 4 is significant because it splits the fructose1,6 biphosphonate into glyceraldehyde-3-phosphate (GAP) and dihydroxyacetone phosphate (DHAP).
