B2 — Cell Organisation Flashcards
What are large multicellular organisms made up of
They are made of organ systems
What are similar cells organised into
They are organised into tissues
What are the 3 types of tissue
The three types of tissue are muscular, glandular and epithelial
What are tissues organised into
They are organised into Organs
What are organs organised into
Organs are organised into organ systems
Name 3 organ systems
The digestive system, the respiratory system and the cardiovascular system
What are enzymes produced by
Enzymes are produced by living things
Why do enzymes have special shapes
So they can catalyse reactions
What do enzymes need
The right temperate and PH
What do digestive enzymes breakdown
They breakdown big molecules
What do carbohydrases convert carbohydrates into
They covert carbohydrates into simple sugars
What do protease convert proteins into
They convert proteins into amino acids
What do lipases covert lipids into
They convert lipids into fatty acids
What does bile do
It neutralises the stomach acid and emulsifies fats
What is the breakdown of food catalysed by
It’s catalysed by enzymes
What solution do you use when testing for testing sugars
You use Benedict’s solution
What solution do you use when testing for testing for starch
You use iodine
What solution do you use when testing for testing for proteins
You use biuret solution
What solution do you use when testing for testing for lipids
You use ethanol
Where are the lungs
They are in the thorax
What do the alveoli carry out in the body
They carry out gaseous exchange
What is the measurement for breathing rate
Breaths per minute
Why does the heart contract
It contracts to pump blood around the body
What are arteries designed to do
Carrying blood away from the heart
What are capillaries designed to do
They are designed for exchange of materials
What are veins designed to do
Veins are designed to pump blood into the heart
What do red blood cells carry
Oxygen and haemoglobin
What shape are red blood cells
Biconcave disc
What do white blood cells defend against
They defend against infection
What do platelets help with
They help with clotting the blood
What is plasma
Plasma is the liquid that carries everything in the blood
What do stents do
They keep arteries open
What do statins do
They reduce cholesterol in blood
What is cancer
Cancer is uncontrolled cell growth
