Respiration Flashcards
(29 cards)
Give the chemical equation for aerobic respiration
Glucose+ Oxygen ➡️ Co2+ water (+energy)
Give the chemical reaction of fermentation
Glucose➡️ Co2+ ethanol (alchohol)
True or false respiration is the same as breathing. Explain your answer.
False. Respiration is not the same as breathing- it is one of the key features of life (MRS GREN) and is when cells process energy during the breakdown of starch.
Where in a plant cell does respiration occur?
In the mitochondria
What do we need energy for?
Movement, absorbing food, building cells, sending nerve signals
What is anaerobic respiration?
It is the breakdown of glucose without any oxygen involved.
Give the formula for anaerobic respiration
Glucose ➡️ lactic acid
What is lactic acid?
It is a toxic substance which builds up in cells as anaerobic respiration occurs
How does the body rid of lactic acid afterwards?
The lactic acid is broken down with oxygen- this is called the oxygen dept
True or false lactic acid is produced when an animal id doing intense exersize
False lactic acid is only a product of anaerobic respiration in humans
Which organisms would ferment?
Some plants and microorganisms like yeast ferment
Explain what the oxygen debt is
the oxygen debt usually occurs after anaerobic respiration has occured (Often after intense exersizes) where requires extra oxygen to break down the lactic acid building up in the muscles. This is why you will usually breathe faster after exersize.
Why would 37 degrees be a good temperature for yeast to grow?
37 degrees is the average body temperature so yeast is more used to growing in that temperature
What is the carbon dioxide produced during fermentation used for?
It is used to help bread rise.
put cell, organism, tissue, organ system and organ in the correct order
cell, tissue, organ, organ system, organism
What is an arterie?
Thick blood vessels which carry blood away from the heart. They have a very thick muscle wall and a very small hole to allow the blood to flow through at very high pressure.
What is a Vein?
Blood vessels which carry blood to the heart. They are quite thin with large holes, this lets blood through at a very low pressure.
What is a capillarie?
A blood vessel which rids of waste products like carbon dioxide and deliver oxygen and nutrients to the cells aswell as connect capilaries and veins together. They are the smallest tyoe of blood vessel
True or false arteries carry blood to the heart
False
True or false veins carry blood to the heart
True
True or false arteries carry blood away from the heart
True
true or false veins carry blood to the heart
true
What are the components of blood?
Red blood cells- carry oxygen and carbon dioxide
Plasma- the liquid substance contains the nturients, hormones and protiens
White blood cells- immune system
Plateles- to repair damaged blood vessels (Stop bleeding from occuring)
What are platelets used for in the blood?
to repair damaged blood vessels (Stops bleeding)
