(44 cards)
What’re the six main nutrients
Carbohydrates
Proteins
Fats/lipids
Minerals
Vitamins
Water
What are the two things carbs are separated into and how fast do they release glucose into our body
Simple carbs - release glucose into our body fast
Complex carbs - glucose is absorbed more slowly into the body
Which ones are simple carbs and which are complex
Monosaccharides
Disaccharides
Polysaccharides
Simple - monosaccharides disaccharides
Complex - polysaccharides
What are monosaccharides disaccharides and polysaccharides made up of
Monosaccharides - single sugar molecule
Disaccharides- 2 monosaccharides linked together
Polysaccharides - many sugar molecules linked together
What’s for formula for glucose
C6H12O6
Give me examples of monosaccharides disaccharides and polysaccharides
Monosaccharides - glucose fructose galactose
Disaccharides- sucrose (glucose+fructose) lactose (glucose+galactose) maltose (glucose+glucose)
Polysaccharide - starch glycogen cellulose
Describe simple carbs
Simple
- fast released carbs
- increase blood sugar rapidly and get a quick release of energy
- to many simple carbs can lead to obesity and high cholesterol
- when to many simple carbs are consumed the excess glucose is stored as body fat
Describe complex carbs
Complex
- absorbed more slowly into the body
- healthier way of eating
- reduces risk of obesity
What are proteins needed for
To repair organs and tissues
Transport molecules
Send messages from on organ to another
Help combat disease
What are amino acids and what are they broken down into
They are small parts that make proteins
And broken down into essential and non-essential amino acids
What are essential and non-essential amino acids
Essential can’t be created within the body so must be provided in diet
Non-essential can be created in the body
What do amino acids do
Break down good
Grow and repair body tissue
Make hormones and brain chemical
Provide energy source
Maintain healthy skin hair and nails
Build muscle
Boost immune system
Sustain a normal digestive system
What is the structure or peptides dipeptides and polypeptides
Peptides - short chain of amino acids linked together by peptide bonds
Dipeptides - consist of only two amino acids and are linked together by one peptide bond
Polypeptide - long chain of amino acids
What are is included in lipids and what is the use of lipids
Lipids include fats and oils
Used for insulation
Used to make cell membrane
Used as an energy store
What are fats and oil made up of
3 fatty acids and glycerol molecule
What is fats and oils at room temp
Fats are solid at room temp
Oils are liquid at room temp
What’re the different roles and functions of vitamins
Regulate body functions
Keep body healthy
Promoting resistance to disease
What are vitamins
Organic nutrients that are essential for nutrition and normal growth
What do we need minerals for
The development and maintenance of the skeletal structure
To regulate water exchange in the body
For the transmission of nerve impulses and muscle contraction
What is water essential for
SURVIVAL
What’re the two types of carnivores and what do they eat
Obligate - rely on just animal flesh
Facultative - also eat non-animal food
How does the tongue saliva oesophagus and stomach help in digestion
Tongue - help move food around and pushed it to the next part of the digestive system
Saliva - lubricantes the mouth, helps swallow food, produces digestive enzymes
Oesophagus - transports food to stomach via peristalsis
Stomach - chemical digestion is facilitated by churning action
What is chyme
It’s a mixture of partially digested food and gastric juices
What are villi and microvilli a part of
They are a part of the small intestines
