Glycogen phosphorylase catalyzes the removal of glucose from glycogen. The AG' for this reaction is 3.1 kJ/mol. Calculate the ratio of [P] to (glucose 1-phosphate] when the reaction is at equilibrium. [P://[glucose 1-phosphate) = 3.494 :1 The measured ratio [P]/[glucose 1-phosphate) in myocytes under physiological conditions is more than 100:1. What does the measured ratio [P://[glucose 1-phosphate) indicate about the direction of metabolite flow through the glycogen phosphorylase reaction in muscle? Metabolite flow is from glucose 1-phosphate to glycogen. Metabolite flow is from glycogen to glucose l-phosphate. The reaction is at equilibrium, and there is no net metabolite flow. Why are the equilibrium and physiological ratios different? Glucose 1-phosphate production is more rapid than its removal. O The high ratio maintained under physiological conditions prevents glucose 1-phosphate production. The rate of glucose 1-phosphate removal is greater than its rate of production. O Glycogen phosphorylase catalyzes glycogen synthesis under physiological conditions. What is the possible significance of this difference? The glycogen phosphorylase reaction is the regulatory step in glycogen breakdown. Inorganic phosphate (P:) regulates glycogen phosphorylase allosterically. The difference occurs because myocytes are frequently deficient in pyridoxal phosphate. The physiological ratio reflects the ability of muscle to produce glucose from glucose 1-phosphate.

Scientific research influenced the green revolution as It resulted in the development of specialized crops and new technology designed to grow as much food as possible. The correct option to this question is B.

The beginning of the Green Revolution is often credited to Norman Borlaug, an American scientist with an interest in agriculture. In the 1940s he began his research in Mexico, developing new disease-resistant, high-yielding wheat varieties. The Borlaug wheat variety combined with new mechanized farming techniques allowed Mexico to produce more wheat than its population needed, and by the 1960s it was a wheat exporter. Prior to using these varieties, the country imported almost half of its wheat supply.

Answer: Heterozygous, as related to genetics, refers to having inherited different versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is heterozygous for a genomic marker has two different versions of that marker. By contrast, an individual who is homozygous for a marker has identical versions of that marker.

Organisms can be homozygous or heterozygous for a gene. Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous. People with CF are homozygous recessive. Since Huntington's disease is autosomal dominant, people with the disease can be either homozygous dominant or heterozygous.

Dendrites of the postsynaptic neurons are the structures that receive chemical messages -neurotransmitters- from the presynaptic neurons. The correct option is D. Dendrites.

Neurons are cells that communicate with each other through the transmition of nervous impulses.

Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.

Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.

During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.

The neurotransmitter is a molecule that travels through the synaptic space forward to the dendrites of the other neuron or to the effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.

This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.

Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.

According to this framework, when two neurons communicate, the neurotransmitter released by one of them reaches the receptors located in the dendrites of the postsynaptic cell.

Dendrites are the structures that receive chemical messages from the other cells.

The correct option is D. Dendrites.

Maize reproduces sexually while rhizopus reproduces both sexually and asexually.

Rhizopus belongs to a group of organisms in the kingdom Fungi. Maize, on the other hand, belongs to a group of organisms in the kingdom Plantae.

Rhizopus is able to reproduce both sexually and asexually. Sexual reproduction is by the fusion of compatible hyphae - one carrying the + strain and the other the - strain.

Asexual reproduction in rhizopus is by the formation of asexual spores - sporangiospores and chlamydospores.

Maize is only able to reproduce sexually. The male gamete in the form of pollen pollinates (fertilizes) the female gamete in the form of ovule or egg. Double fertilization occurs to form a seed coat that nourishes the zygote.

It is an example of Fixed Action Patterns.

A fixed action pattern (FAP) is a predetermined set of behaviors that happen in a predetermined order in response to a sign stimulus, which is an external stimulus. The behavior is "fixed" because it is essentially unchanging and behaves consistently among members of a species.

FAPs are inherent, which means that the animal is born with the capacity to engage in the behavior and does not require learning. FAPs are also typically finished after being triggered. The ability to instinctively identify and attack prey or, as in the case of sticklebacks, the ability to produce more young that can survive to adulthood are just two examples of how these behaviors may be crucial to improving an animal's fitness.

Cellular respiration and photosynthesis are similar in that both produce ATP molecules, which are the main energy source for cells.

Cellular respiration is the biochemical process of converting the chemical energy stored in food molecules into ATP molecules, which are the energy currency of cells. This process occurs in the mitochondria of cells and is a vital part of the energy cycle that maintains homeostasis and drives the metabolic activities of cells. During cellular respiration, oxygen is consumed and carbon dioxide is released as a by-product. The process involves the breakdown of food molecules, such as glucose, into smaller molecules, such as pyruvate, and the subsequent transfer of electrons from these molecules to electron acceptors, such as oxygen, to create ATP.

ATP stands for adenosine triphosphate, and it is a molecule that stores and transports energy within cells. Photosynthesis produces ATP by converting energy from light into a form of chemical energy, while cellular respiration produces ATP by breaking down glucose molecules.

A gene that is expressed only in the homozygous state is known as recessive.

Alleles of a gene can be either dominant or recessive. Dominant alleles show their effect even when they are present in the heterozygous state. The recessive alleles only show effect when in homozygous state. Only the homozygous individuals, which are the ones having two copies, will experience the effects of recessive alleles.

For example, the allele for blue eyes is recessive and is represented by "b" and the allele for brown eyes is dominant and is represented by "B". If the genotype of the individual is BB or Bb, they will have brown eyes as they B is the dominant allele. If the genotype of the individual is bb, they'll have blue eyes as b is a recessive allele and will only show effect in homozygous condition.
