biology Flashcards
respiration is a
chemical reaction
respiration occurs in all living
cells and releases energy from glucose
aerobic respiration occurs
with oxygen
anaerobic respiration occurs
without oxygen
aerobic energy releases
more energy but more slowly
anaerobic energy releases
less energy but more quickly
aerobic energy equation
Glucose+ Oxygen —–> Carbon dioxide and water
anaerobic energy equation
Glucose—–> Lactic acid
Respiration occurs
in the mitochondria
mitochondria is found
in the cytoplasm
specialised cells are
cells that have a particular adaptation to help them complete a specific function
examples of specialised cells
red blood cells, sperm, eggs nerve cells muscle cells and villi
red blood cells dont have a
Nucleus
red blood cells dont have a nucleus which helps
carry more oxygen
red blood cells are biconcave meaning
they can absorb oxygen faster
red blood cells are round so they can
flow through capillaries easily
Oxygen is needed in
Respiration
The ovaries two jobs are
to contain underdeveloped eggs and to make female sex hormones
Gametes are the male and female
sex cells
the female gamete
is the Ova
the male gamete
is the sperm
when the male and female gamete join together
it is called fertilisation
ovary is connected to the uterus
by am oviduct
the oviduct is lined with
cilia
