When a molecule is made up of one sugar unit, its called a monomer.
Eg. Glucose, galactose, fructose
When a molecule is made of more than one sugar units, its called a polymer.
Eg. Cellulose, glycogen
Polymers are usually macro molecules.
Answer:
Letter a. Yes, yeasts can exist in an oxygen-poor environment.
Explanation:
Mitochondria are an organelle that we can find in the majority of eukaryotic cells. Mitochondria help in produces the energetical molecule of ATP. We start with one molecule of glucose that passes through a process called glycolysis to convert glucose into pyruvate. This pyruvate molecule can follow two pathways: when oxygen is available the pyruvate enter into the Krebs cycle and proceeds to the respiratory chain in the mitochondria, when oxygen is not present, pyruvate pass into another pathway, one is the alcoholic fermentation producing ethanol and dioxide of carbon.
As yeast are a eukaryotic organism, they have mitochondria and can grow in the presence of oxygen. When oxygen is absent yeast can grow using the fermentation pathway producing alcohol.
Answer:
<u>Neostigmine act as Cholinesterase inhibitors.it inhibits enzyme Cholinesterase as a competitive reversible antagonists. </u>
This is an enzyme which normally breakdown neurotransmitter acetycholine at the neuromuscular junction (cholinergic synapses). and therefore the termination of synaptic neurotransmission.
<u>Acetycholine is a cholinergic neurotransmitter that ensures transmission of cholinergic nervous signal/synapses at neuromuscular juntion.</u>
Neostigmine inhibiting actions therefore promotes accumulation of acetycholine and thus extended the transmission of cholinergic synapses,
This is expllained the reason why neostigmine mechanisms is used for treatment of neuromuscular disorders e.g autoimmune diseases Myasthenia graviis (weakling of body muscles.
T<u>herfore to counter the advserse effect of Neostigmine</u> ;
which include; salvation, head ache, increased muscus secreation,muscle itching,dizziness,
Intravenous application of 0.04mg/kg/dose of <em> atropine sulphate</em> should be given with respect to each dose of Neostigmine administered.
