As a result of low brain-derived neurotrophic factor (bdnf), most people with depression exhibit __________, __________, and ___

kenny6666 [7]

As a result of low brain-derived neurotrophic factor (BDNF), most people with depression exhibit neuronal loss, learning disabilities, and reduced production of new hippocampal neurons.

Brain-derived neurotrophic factor (BDNF) manages glucose and energy metabolism and controls exhaustion of β cells. Reduced levels of BDNF are associated with neurodegenerative disorders with neuronal loss, such as Alzheimer's disease, Parkinson's disease, and Huntington's disease.

kirill115 [55]

Answer:

The answer is reciprocal chromosomal translocation

Explanation:

The Philadelphia chromosome (Ph) is the truncated chromosome 22 generated by the reciprocal translocation t(9;22)(q34;q11) and was first identified in 1960 in a patient with CML [3]. Translocation of the proto-oncogene tyrosine-protein kinase (ABL1) gene located on chromosome 9 to the breakpoint cluster region (BCR) gene located on chromosome 22 results in a BCR-ABL1 fusion gene on the Ph [4, 5]. Three BCR-ABL1 fusion gene hybrids encode BCR-ABL1 protein isoforms p210, p190, and p230, which have persistently enhanced tyrosine kinase (TK) activity. These aberrantly activated kinases disturb downstream signaling pathways, causing enhanced proliferation, differentiation arrest, and resistance to cell death [6, 7]. Tyrosine kinase inhibitors (TKIs) targeting the BCR-ABL1 protein are the most successful targeted therapy for Ph-positive leukemia.

All organisms undergo glycolysis. The final product of glycolysis is pyruvate, a 3-carbon molecule. When will pyruvate undergo f

Naddik [55]

Answer:

The correct answer is given below:

Explanation:

Depending upon the availability of oxygen, pyruvic acid follows, a variety of metabolic pathways.

In the absence of oxygen or under anaerobic conditions, the pyruvic acid further metabolised into one of three pathways: lactic acid fermentation, alcohol fermentation and cellular anaerobic respiration. During fermentation or anaerobic respiration 2 ATP is produced.

In the presence of oxygen or under aerobic conditions, the pyruvic acid completely oxidised to carbon dioxide, water and 38 ATP.

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.
