Nutrition And Energy Systems Flashcards
Rough ER
Transports and finishes proteins and other biological molecules
Ribosomes
Make proteins
Golgi complex
Packaging proteins and distributes
Lysosomes
Clean things up
Digesting
Nucleus
Contains and protects DNA
Mitochondria
Site of respiration and generates energy
Lipolysis
The breakdown (catabolism) of adipose tissue by glucagon and adrenaline to increase blood sugar
Glycolysis
Glucagon and adrenaline stimulate the breakdown of glycogen in the liver to increase blood glucose levels during long periods of exercise and fasting
Lipogenesis
When insulin inhibits fat breakdown and converts excess glucose into body fat
Balanced diet
A diet that provides all nutrients in the right amount in order to maintain health
Dietary recommendations
Recommended amount of essential nutrients of the diet
Essential aminos
8 aminos that are not synthesized in the body and must be ingested
Nonessential aminos
The remaining 12 aminos manufactured by the body
Amino acids
The building black of proteins joined by peptide bonds. 20 diff amount of aminos
Role of proteins in the body
Tissue synthesis ( anabolism) constituent of plasma membranes , globular proteins make up enzymes
Protein
Contain carbon, hydrogen, oxygen and nitrogen ( Nitrogen must be present)!!!
Unsaturated
Contain one or more double bonds along the carbon chain
Originate from plant based food
Lost some unsaturated foods
Olives Peanut/ cashews Avacado Canola and sunflower oil Rapeseed
Saturated
Contain only single bonds between carbon atoms
All other bonds attach to hydrogen
List some saturated foods
Originate animal source
Meat, poultry, full fat dairy
Coconut oil and Palm
Roles of lipids
Hunger suppressor
Transport fat solvable vitamins
Thermal insulation
Energy reserve
Nutrients
GMB
Substance needed for growth , metabolism and bodily functions
Micronutrients
Nutrients required by humans in small amounts to orchestrate a wide variety of physiological functions but are not made by the organism
List the micronutrients
Fiber vitamins mineral
