Glucose and ATP are organic compounds composed of carbon, hydrogen and oxygen. Other than these three elements, ATP contains Phosphorus and Nitrogen. Cellular respiration breaks down glucose into water and carbon dioxide producing 38 net ATP molecules. ATP is the energy containing nucleotide in cells while the energy found in glucose is used to make ATP. The key difference between glucose and ATP is the composition of these two molecules.
What is Glucose?
Glucose is a simple sugar which is widely used in living organisms. The chemical formula of glucose is C6H12O6. It is a monosaccharide which functions as a precursor for many carbohydrates found in the organisms. In plants, glucose is produced by photosynthesis and used as a substrate for energy production. In animals, glucose is a prime energy source. In prokaryotes, glucose subjects to either aerobic respiration, anaerobic respiration, or fermentation and converts into energy molecules. Therefore, glucose can be considered as one of a primary energy source of living organisms.
Glucose is broken down completely to water and carbon dioxide by aerobic respiration. It starts with electrolysis and going via Krebs cycle and electron transport chain. In the end, it converts the energy in the nutrient glucose into 38 ATP and other two waste products. Anaerobic respiration produces less number of ATP from a glucose molecule since glucose is undergoing incomplete combustion. Some microorganisms ferment lactose to lactic acid or alcohol produce energy under anorexic conditions. All these processes use glucose as the starting substrate for ATP production.
What is ATP?
Adenosine triphosphate (ATP) is the energy currency in living cells. It is a nucleotide composed of three major components; namely, ribose sugar, triphosphate group, and adenine base. ATP molecules bear high energy within the molecules. Upon an energy request for growth and metabolism, the ATP hydrolyses and releases its energy for cellular needs. Three phosphate groups are responsible for the function of the ATP molecule because the energy is stored in ATP molecule inside the phospho-anhydride bonds between phosphate groups. The most commonly hydrolyzing phosphate group of the ATP molecule is the farthest phosphate group (Gamma-phosphate) from the ribose sugar.
ATP molecule bears high energy within it. Therefore, it is an unstable molecule. Hydrolysis of ATP is always feasible via an ergonomic reaction. The terminal phosphate group removes from the ATP molecule and converts into Adenine phosphate (ADP) when the water is present. This conversion releases 30.6 kJ/mol energy to the cells. ADP converts back into ATP immediately inside the mitochondria by ATP synthase during the cellular respiration.
Answer:
a. substantia nigra
b. substantia nigra (it is repeated)
Explanation:
Parkinson's disease is a neurodegenerative disease that is caused by the death of neurons that release the neurotransmitter dopamine in the <u>substantia nigra</u>, or locus niger, -a region of the brain that regulates brain circuits that give the 'orders' to initiate voluntary movements- .
The lack of this neurotransmitter leads to the occurrence of the main symptoms suffered by patients: decreased movements, muscle stiffness, postural instability and tremor. These failures are generated by the abnormal way in which neurons work in the absence of dopamine through a mechanism that is not known in depth.
It is the second most frequent neurodegenerative disease, after Alzheimer's disease, with a prevalence of 2% in people over 65 years. The characteristic symptoms of stiffness, bradykinesia and tremor are associated with losses of neurons in the substantia nigra and dopamine depletion in the striatum. There are large cytoplasmic inclusions, called Lewy bodies, which are the pathological mark of the disease and appear predominantly in neurons that contain melanin of the nigra substance. Genetic studies in a subgroup of families with Parkinson's disease with autosomal dominant inheritance found a locus on chromosome 4q-21 23 and a mutation in the gene that encodes a synaptic protein, α-synuclein.
Answer:
Mutualism
Explanation:
In biology, the term <em>symbiosis </em>refers to close and often long-term interactions between organisms that belong to different species. There are three main types of symbiotic relationships:
- mutualism - both organisms benefit from their relationship
- commensalism - one organism benefits, while the other doesn't benefit or suffer any harm
- parasitism - one organism causes harm to the other
In the given scenario, both the bird and plant benefit from their relationship. The bird gets food, while the plant reproduces more easily. This is why their relationship is an example of mutualism.
Your answer is A interphase.
