Answer:The energy in glucose cannot be transformed, but the energy in ATP can be used to do cellular work.

Glucose can be renewed and reused in cellular energy processes, but once ATP is used, it cannot be reused

Explanation:

Glucose contains more energy than ATP. However, the energy that glucose contains is not in a form that's immediately available for use. It has to undergo cellular respiration to form ATP. ATP has energy that a human body cell can use right away. Intact ATP molecules break glucose down to make it into a more usable form.

Fantom [35]

Answer: Cori cycle consumes more energy,it expended 4ATPs, therefore with poor efficiency.

1 Glyceraldehyde 3-phosphate dehydrogenase.

it is an enzyme which functions in Glycolysis only, to breakdown the 6th. step of of subtrate phosphorylation of glucose.

2. glucose-6-phosphotase.

This is the enzyme that works in gluconeogenesis only to intiaate its first step. it hydrolyse glucose-6-phosphate , to generate glucose and phosphate.

Alcohol dehydrogenase

This enzyme does not play any role with both pathways.Rather it catalysis the oxidation of primary and secondary alcohols to aldehyde and ketones. The reaction involves reduction with NADH+

phosphoenopyruvate carboxykinase

functions in the gluconeogensis pathways for conversion of oxaloacatate to phosphoenopyruvate and CO2.

Phosphofructokinase-1

function as regulatory enzyme of glycolysis to convert fructose-6-phosphate and ATP hydrolysis to glucose 1, 6, bisphosphate and ADP respectively.

Phosphoglycerate mutase.

An enzyme involved in glycolytic pathway, it catalysed the 8th step of glycolysis.

Hexokinase- an enzyme of glycolytic pathway invloved in phosphorylation of glucose, to intiate the process of glycolysis.

Pyruvate dehydrogenase

This is an enzyme that converts pyruvate to acetyl Co-A.

therefore it plays no role in the two pathways, because glycolytic pathway ends with pyruvate production.

"interpret the diagram"

Pachacha [2.7K]

1. The glutamate causes an influx of ca2+ ions into the nerve cell akin to what occurs during depolarization. However, this occurs excessively without regulation (due to excessive stimulation by the glutamate) that eventually causes nerve injury through cytotoxic edema.

2. When the ca2+ levels are lowered during stroke, then nerve cell injury would be obviated hence enabling the chances of restoration of nerve cell function. This would happen because there would be no excess calcium ions to influx when the NMDA receptors are excessively stimulated by the glutamate molecules.

Explain what friction corollas and a low pressure gradient does to an air parcel?

Kipish [7]

Answer with Explanation:

Coriolis Force - refers to the fictitious force that acts perpendicularly to the direction of a rotating motion.

Air parcel - refers to a body of air that is "imaginary."

Pressure gradient - the change in pressure across a given distance.

Pressure gradient force - the net force that is being directed from high pressure to low pressure.

When an air parcel is at rest, the pressure gradient force acts upon it. It will then move from high pressure to low pressure.

However, when the air parcel starts to be in motion, its direction will be changed with the help of the Coriolis force. Thus, it moves to the right side of the Northern hemisphere.

Once the speed of the wind increases, the change in direction of the air parcel increases. This happens until the pressure gradient force and the Coriolis Force are equal in magnitude. When this happens, the wind will start blowing parallel to the points of equal pressure. The wind will now then be referred to as in "geostrophic balance."

When friction happens, the geostrophic balance breaks. The flow of the wind will be slowed down. This means that the Coriolis force will also be lessened. The air parcel will then move towards the lower region.

Alicia is being tickled by her older sister. which divisions of the nervous system are receiving the signals from her sister’s f

Finger [1]

In this case, when Alicia is being tickled by her older sister, the divisions of the nervous system which are responsible for receiving the signals from her sister’s fingers are called somatosensory cortex and anterior cingulated cortex nervous system.

When you are touched lightly, the effect of having that ticklish sensation is caused by the analysis of two regions of the brain. For example, when our brain analyses the pressure of the touch, this is the work of the somatosensory cortex. On the other hand, as soon as something touches your skin, the signal sent from the skin's sensory receptors also passes through the anterior cingulated cortex.This is where the pleasant feelings are governed.
