26
What does Glucose + oxygen equal
water + carbpon dioxide + energy
27
What is the anaroebic respiration equation in general
glucose=carbon dioxide + lactic acid + energy
28
What is areobic respiriation
Aerobic respiration occurs with oxygen and releases more energy but more slowly.
29
What is anaroebic respration
Anaerobic respiration occurs without oxygen and releases less energy but more quickly.
30
What is Respiration
Respiration is a chemical reaction which occurs in every one of the cells in the human body. It releases energy stored in glucose and without it, these cells would die.
31
What is the equation for arobeic respiration
glucose + oxygen → carbon dioxide + water
32
What is the equation for anarobic respiration in human and animal muscles
glucose → lactic acid
33
In which cell component does respiration occur?
Mitochondria within the cytoplasm. Genetic information is held within the nucleus. The cell membrane controls what enters and exits the cell.
34
What are the reactants in aerobic respiration?
The reactants in aerobic respiration are glucose and oxygen.
35
What is produced in anaerobic respiration in humans?
Lactic acid is produced in anaerobic respiration in humans. Carbon dioxide and water are produced in aerobic respiration. Glucose is the reactant. Alcohol is produced in fermentation by yeast and bacteria.
36
What is true of anaerobic respiration compared with aerobic?
Anaerobic respiration releases less energy faster.
37
What is missing for anaerobic respiration to occur?
Anaerobic respiration occurs without oxygen.
38
Which type of respiration releases more energy, more slowly?
Aerobic respiration releases more energy but more slowly than anarobic
39
True or false? Respiration is the same as breathing.
False
40
What can the build-up of lactic acid lead to in muscles?
Cramp
41
True or false? Aerobic means in the presence of air.
False
42
How do you know when a bread is made by using yeast
Because its risen due to carbon dioxide gases
43
Whats another food or drink made using yeast
Beer
44
What conitions is best for yeast reproduction
sugar with water at warm temp
45
By what method does fermentation occur in yeast
budding
46
What conditions do fungi need to grow and reproduce
sugar, warmth and moisture
47
what equation summarises respiration in bacetria
glucose- lactic acid
48
what is anaroebic
doesnt need oxygen
49
why do bacteria reproduce faster in warmer condiitons
enzymes work faster when its warm
50
What effect do yogurt-making bacteria have on milk
they make it sour
51
What does a flagellum do
moves the cell
52
what does chromosome do
contains the information to control the cell
53
where are protocists found
in all habitats
54
What do protocists feed on
bacteria
55
Where do protocists mov eon
tiny little hairs
56
Can protocists sometimes be green
yes because of chloroplasts
57
pseudopods help amoebas move
because some dont move
58
How do protocists eat cytoplasm
it surrounds it then englufs it
59
how do pseupods move
they stretch out from the cell and used to pull the rest of th cell towards them
60
What are pseupods for
they help amoebas move and they stretch out their cytoplasm
61
why does algae have an eyespot to detect light
so they can produce photosynthesis
62
where does algae get its energy from
from the light when they photsyntheies
63
what resources do protocists need to grow well
moisture and warmth
64
examples of fungi
mushrooms yeast and mould
65
do fungi cells have a nucelus
Yes
66
do fungi cells have chloroplasts
No
67
What is a ringworm
A common skin diease thought to be caused by worms
68
How could of David Gruby discover a fungus in the rings.
by a microscope
69
how do yeast reproduce
use budding
70
what is budding
asexual reproduction
71
what is the product with glucose
from the digestive system
72
what is the product of carbon dioxide in anaroebic respiration
waste product exhaled (poisonnous)
73
what does aroebic respiration release
energy for yeast cells and produces more carbon dioxide
74
why do we add yeast when making bread
make it rise
75
what is fermentation
when yeast respires anaoerobically and is used to make wine and beer
76
why is air kept out of juice mixture
make sure it ferments
77
is yeast part of the fungi kingdom
yes
78
is glucose a limiting factor for yeast to grow
yes
79
what is chromosomal DNA
giant loop of DNA containing most of the genetic material
80
what si the Flagella
long whip like sctructure that allow the bacteria to move themselves
81
what is teh slime coat
layer surroudning the bacteria cell to protect it from enviromental dangers
82
why does a bacteria cell need a flagellum
help it move themselves
83
why does a bacteria cell need a slime coat
to protect itself from enviromental dangers
84
does a bacteria cell have nucleus
no
85
what is the difference between budding and binary fission
Cytoplasmic division
86
what is binary fission
a type of asexual reproduction
87
does temperature and glucose effect the growth rate of bacteria
Yes
88
what is bacteria
a member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organized nucleus, including some that can cause disease.
89
is bacteria unicellular
yes
90
What do bacteria divide by when they multiply
binary fission
91
why does yeast population stop growing
limiting factors
92
what is the equation for photosynthesis
Carbon dioxide + Water =( SUNLIGHT) Glucose + Oxygen
93
is photosynthesis the same as areobic respiration
No because areobic respiration uses oxygen and produces carbon dioxide and photosynthesis uses carbon dioxide and produces oxygen
94
Why do anmials rely on photosyntheis
Photosynthesis is really important for animals, including humans because
without photosynthesis we wouldn’t have food because it converts energy from the sun into chemical energy for the food chains.
photosynthesis keeps the levels of oxygen and carbon dioxide in the atmosphere in balance – without it we would very quickly run out of oxygen.
95
what do plants need for photosynthesis
carbon dioxide
water
light
96
what do plants make by photosynthesus
glucose (sugar)
oxygen
97
what do chloroplasts contain to make them green
chlorophyll
98
What is chlorophyll
green pigment, present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis.
99
Where do plants get carbon dioxide from
Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun.
100
what is the role of a phagocyte
Engulf and destroy bacteria
101
what is the role of a b-cell
Makes infection-fighting proteins called antibodies
102
what is the role of a t cell
destroy body cells that have been infected by the pathogen
