Phosphofructokinase is an enzyme that acts on fructose 6-
phosphate at an early step in glucose breakdown. Regulation of this enzyme controls
whether the sugar will continue on in the glycolytic pathway. Considering this graph,
under which condition is phosphofructokinase more active? Given what you know about
glycolysis and regulation of metabolism by this enzyme, explain the mechanism by which
phosphofructokinase activity differs depending on ATP concentration. Explain why it
makes sense that regulation of this enzyme has evolved so that it works this way.

Answer:

Fight or flight

The amygdala activates this fight-or-flight response without any initiative from you. When that part of your brain senses danger, it signals your brain to pump stress hormones, preparing your body to either fight for survival or to flee to safety.

900 MHz devices are more expensive and provide slower data output.

WLAN is defined as a wireless distribution of network used for two or more devices.

The industrial, scientific, and medical (ism) band is a WLAN that makes use of radio frequency

for domestic network purposes.

A gigahertz connection delivers more bits per second more than a megahertz connection.

Therefore, 900 MHz cannot be compared with 2.4 gigahertz (ghz) and 5 ghz frequency systems because 900 MHz devices are more expensive and provide slower data output.

When you are exposed to bright light, cells in the retina detect the stimulus and send it to the brain for processing. The brain commands the iris to constrict and decrease pupil size.

The structure that serves as a receptor in this system is Retina

Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.

The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.

These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.

Thus, Retina is the answer.

The Motor Effect

Explanation:

:)

Answer:

The Motor Effect

Explanation:

According to the chemiosmotic hypothesis, ATP is produced by due to the proton gradient created across the mitochondrial membrane. The essential components required for chemiosmosis are proton pump, proton gradient and ATP synthase. ATP synthase is an enzyme which helps in ATP synthesis. The enzyme ATP synthase has two part

F0 andF1.F0 is the part which transports protons across the membrane as a transmembrane channel while configuration changes in F1

activates the enzyme. They phosphorylate ADP i.e., add one more phosphorus group to the ADP and converts ADP(adenosine diphosphate) to ATP (adenosine triphosphate). The proton gradient developed across the membrane is the driving force of ATP synthase.

The correct answer is Eukarya has similar evolutionary traits to Archaea.

Thus, option "D" is correct.

The six kingdom classification by Carl Woese divided the organisms into three domains which are Bacteria, Archaea, and Eukarya. the archaea and Eubacteria are micro-organisms while plants, animals, and microorganisms such as fungi and protists under Eukarya.

The Eukaryotes are more closely related to the Archaea than bacteria as:

1. Transcription - they both use same TATA-binding proteins-TFIIB and elongation factors.

2. Translation- First amino acid during protein synthesis is the same in both the organisms which is methionine.

3.  Histones - same histones are involved in the packaging of DNA.  

4. Sensitivity to antibiotics- both are insensitive to antibiotics.

Thus, Eukarya has similar evolutionary traits to Archaea is the correct answer, option "D" is correct.

Regulating hormones from the hypothalamus first enter into the hypophyseal portal system.

The hormones produced by the hypothalamus and secreted by the neurohypophysis are antidiuretic hormone and oxytocin. Antidiuretic hormone promotes an increase in urine concentration, as it ensures greater reabsorption of water by the kidneys.

It is the hypothalamus that produces the antidiuretic hormone and oxytocin, which will be secreted by the neurohypophysis.

Because one of the two strands of a replicated DNA molecule is newly synthesized and the other is the original template, DNA replication is said to be a semi-conservative process.

DNA replication may be defined as the biological process that involves duplicating a DNA molecule comparable to the construction of two DNA molecules.

DNA replication is proceeded by the semiconservative model, which means that the parental double helix is half conserved, and each parental single strand remains intact.

Therefore, it is well described above.

The process by which photoreceptors become activated when the photopigments within the discs of the cells are altered by light entering the eye is phototransduction.

The photoreceptor responds to light stimulation by changing its resting membrane potential, resulting in a change in the neurotransmitters that it releases.

It should be noted that receptors bind to ligands and causes response in the immune system.

The structures of the neuromuscular junction are apresynaptic region; synaptic cleft and postsynaptic region.

The neuromuscular junction is where a nerve ending joins skeletal muscle tissue. Muscle contraction signals are initiated by chemicals, such as the neurotransmitter acetylcholine, that are transferred from the nerve ending, or motor end plate, to the muscle.

The importance of neuromuscular junctions is the synapse region between skeletal striated muscle fiber and motor axon; whose function is the transmission of the nerve impulse.

A map's legend (or key) provides a list of the features depicted on the map together with the accompanying symbols.

A global graticule and a coordinates grid are often displayed on topographic maps so you can identify the relative and absolute locations of depicted features.

A map is only a two- or three-dimensional depiction of the actual world at a specific time, it is vital to remember this. A map will therefore never be completely accurate.
