Topic 1 Flashcards
Ribosomes
Produce protein and are used to make enzymes
Found in the epithelial cells in the small intestine
Mitochondria
Provides energy for respiration and causes the small intestine to contract via peristalsis
Microvilli
Absorbs digested nutrients & helps to increase the surface area of the small intestine
Cilia
Wafts substance along a tube in the epithelial cells in the Oviduct, trachea
What is inside a plant cell
Ribosomes, cell wall, nucleus, cell membrane, cytoplasm, chloroplast, large vacuole, mitochondria
What is inside an animal cell
Cytoplasm, nucleus, lysosomes, cell membrane, ribosomes, mitochondria, Golgi apparatus,
What is an egg made up of
Haploid nucleus, cell membrane, storage vacuoles, mitochondria
What is a sperm made up of
Mitochondria, acrosome, haploid nucleus, tail
What is a haploid nucleus
A nucleus that has half the number of chromosomes
Magnification= ?/?
Magnification= size of image/ actual size of object
How do you get meters into micrometers
Divide by 1000000
What can protein be broken down into
Amino acids
What makes enzymes work more slowly
When the temperature is below or above optimum
Below: molecules move slowly so they don’t collide into each other as frequently
Above: changes the active site so the substance molecule no longer fits so a reaction won’t occur
Why can’t heat cells produce glucose
They do not have chloroplast or chlorophyll so can’t photosynthesis
What is the function of white blood cells
Are part of the body immune system, help to fight infection
