“What are the effects of chemicals in food and drink on cellular functions?”
Cell functions
Metabolism
Respiration
When the body is able to take in more glucose from food
anaerobic respiration
Anaerobic respiration will decrease
Why
As glucose increases, the body preferentially uses aerobic respiration for energy, so the need for anaerobic respiration decreases.
Alternative Pathways to Generate Energy
aerobic respiration
Aerobic respiration increases.
Why
As glucose increases, the body metabolises it faster, hence aerobic respiration increases to meet energy demands.
main way of producing energy
Movement of substances
photosynthesis
There are no chloroplasts in the human body, photosynthetic activity cannot be carried out. Therefore, the food and drink have no effect on photosynthesis.
Homeostasis
Digestion
Chemicals
Common chemical found in food and drinks
Caffeine
It is found in coffee, most teas, cocoa, chocolate, cola, guarana.
Caffeine is a stimulant that acts on the brain and nervous system
, make you feel more alert and energetic
Caffeine is found in some medications that relieve pain and treat colds and flu. Some appetite suppressants and weight loss products may contain caffeine.
Artificial Sweeteners
Artificial sweeteners may help promote weight loss and blood sugar control.
Artificial sweeteners do not provide the calories or glucose that our bodies need, and they do not activate our bodies' insulin production
Sodium Nitrite
Glucose
Speed up sugar metabolism, promote aerobic respiration, and reduce anaerobic respiration. Provide more energy(ATP) .
Monosodium Glutamate
Monosodium glutamate is a common food additive used to intensify and enhance the flavor of savory dishes
large amounts caused harmful neurological effects and impaired growth and development
this additive is likely to have little to no effect on human brain health as it’s unable to cross the blood-brain barrier
Artificial Food Coloring
suspected harmful
Trans Fat
Eating trans fats has been associated with many negative effects on health, including inflammation, heart disease and diabetes.
Effect
Unable to be determined unite experiment is conducted
