APHY 102 - Exam 3 Nutrition and Metabolism
Questions and Answers
Metabolism
the coordinated process of transforming nutrients into substrates
chemical process your body uses to transform the food you eat into the fuel that keeps you alive
Nutrition consists of
proteins, carbs & fats
Nutrition& metabolism is
connected to maintain the homeostasis in the body, fuel is needed to keep the body going
Metabolism refers
to the sum of all physical and chemical processes by which living organisms are produced and
maintained
Attributes are defined as
Defining characteristics of the concept, what quality must be present for the concept to exist
Attributes
contributes to body structure and/or regulate chemical processes in the body, proper metabolism will
result in the right amount of energy released that the body needs to function
Antecedents
preceding events that influence what comes later; what must happen before the concept can exist
Antecedents are classified as
food can be ingested properly & nutrients can be absorbed, transported, metabolized, and eliminated
There must be adequate ingestion of nutrients & water
Adequate thermoregualtion and a normal Ph level must be maintained for proper metabolic function
to occur
Malnutrition
insufficient/excess intake(leading to failure to thrive or obesity): altered hydration status
low energy/fatigued
Physiological
psychological dysfunction (trouble with ingestion, digestion, absorption & metabolism)
-depression/isolation
Growth & development of delays
decreased bone density
delayed & inadequate healing
illness/muscle wasting
death
, Consequences can be
neg or positive
Metabolic syndrome
A syndrome marked by the presence of usually three or more of a group of factors (as high blood
pressure, abdominal obesity, high triglyceride levels, low HDL levels, and high fasting levels of blood
sugar) that are linked to increased risk of cardiovascular disease and Type 2 diabetes.
Pancreas
a gland organ that produces exocrine glands to help with digestion and endocrine glands that control
blood glucose
Liver
acts as the body's glucose(or fuel) reservoir and helps to keep your circulating blood sugar levels and
other body fuels steady and constant
Liver stores & manufactures
glucose depending upon the body's need
Glucose can made in three ways
1. through eating carbs that form into glucose
2.Glucose is released through stored glucagon-through muscle cells and liver
3. Glucose is newly made through the liver and kidney cells
Diabetes Mellitus
a group of disorders characterized by elevated blood glucose levels(hyperglycemia)
the ability of the body to maintain homeostasis(the balance between actions of glucagon and insulin)
is impaired
Normal fasting blood glucose
less than 100 mg/dl
Prediabetes fasting blood glucose level
100-125 mg/dL(warning signs for type 2 diabetes)
Diabetes fasting blood glucose
126 mg/dL or higher
Normal fasting glucose can be altered if
a person is not eating for 8 hrs or more
Type 1 diabetes
