If heavy exercise produces lots of co2 in the body, will the blood become more acid or more basic?.

The statement: Positive feedback mechanisms tend to enhance the original stimulus so that the response is accelerated, is true.

Positive feedback mechanism occurs for the maintenance of homeostasis. The positive feedback functions to amplify of increase the output of a reaction. For the maintenance of homeostasis, the positive feedback directs the body towards equilibrium.

Stimulus is any signal that stimulates the body to react or simply produce an action. For example, when the body suddenly touches any hot object, the touch acts as a stimulus, for which the action produced is to remove the hand instantly. The nerve cells acts in this process of carrying the signals inside the body.

Epinephrine inhibits salivary gland activity and muscle cell contraction in the airways, yet stimulates glycogen release in muscle cells and heart muscle cell contraction. One hormone could have opposing effects on different organs as e. cells in the different tissues would have epinephrine receptors coupled to different signaling pathways.

A hormone uses a cell signaling pathway to induce a response from a cell and help in the proper functioning of the cell. It depends on the receptors of the hormone in different cells that decide which signaling pathway will be taken by a hormone.

A hormone will have two opposing actions in two different cell types based on the receptors present for that hormone on these cells. The receptors for epinephrine in the muscle cells activate a signaling pathway that stimulates the production of glycogen. Yet, the receptors for the same hormone i.e epinephrine present in the airways inhibit the salivary gland activity.

Although a part of your question is missing, you might be referring to this question:

Epinephrine inhibits salivary gland activity and muscle cell contraction in the airways, yet stimulates glycogen release in muscle cells and heart muscle cell contraction. How could one hormone have opposing effects on different organs?

a. Cells in the tissues that are suppressed do not express an epinephrine receptor.

(A) "The cyanide will prevent movement of electrons along the electron transport chain." will be the likely outcome if mitochondria are exposed to high levels of cyanide when purified cytochrome oxidase is exposed to cyanide, the cyanide binds reversibly and with high affinity to the enzyme’s active site.

An electron transport chain (ETC) is a collection of protein complexes and other molecules that connect protons (H+ ions) across a membrane with the transfer of electrons (through redox processes, where both reduction and oxidation occur concurrently) from electron donors to electron acceptors. a collection of proteins found in mitochondria's inner membrane.

Four multi-subunit big enzyme complexes and two mobile electron carriers work together to transport the electrons from NADH and FADH2 to the ETC. The electron transport chain's enzymes are mostly membrane-bound.

It takes energy to move electrons via the electron transport chain. Adenosine triphosphate (ATP) is synthesized by using the energy from redox processes to produce an electrochemical proton gradient.

Biological fluids regulate pH values using buffers. This is achieved by accepting H⁺ ions when pH is low and donating H⁺ ions when pH is high.

pH is the potential of hydrogen, that gives an idea about the acidity of basicity of a solution. pH can have values ranging from 0 to 14. A pH value of 7 is neutral. Values below 7 are acidic and values above 7 are basic.

Buffers are the solutions that have the ability to resist any change in pH when any acidic or basic component is added to them. A buffer solution consists of a weak acid and its conjugate base or vice versa. The human body consists of natural buffer, which is blood.

Structures called the perforating canals house blood vessels that carry blood from the medullary cavity and periosteum to the osteon.

The blood vessels that go via the central canals can link to the blood vessels in the periosteum that covers the bone through perforating canals, which act as conduits. Trabeculae, or thin, atypically formed plates, are organised in a latticework network to make up trabecular bone.

Osteocytes are found in lacunae that are located in between calcified lamellae in trabeculae, just like osteons are in osteons. Similar to osteons, trabeculae have canaliculi that link the osteocytes. However, each osteocyte can exchange nutrients with neighboring blood vessels since each trabecula is only just a few cell layers thick. Therefore, a central canal is not required.

Therefore, perforating canals house blood vessels that carry blood vessels from the medullary cavity and periosteum to the osteon.

You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. Endoplasmic reticulum (ER) is the place where this observation will begin.

As all enzymes are proteins hence we will begin with the endoplasmic reticulum to study the whole process from the formation of enzymes. The endoplasmic reticulum is the site that plays a central role in the synthesis of a protein.

Ribosomes, the sites where proteins are formed after the translation of mRNA, are present on the membranes of the rough endoplasmic reticulum (RER). After the synthesis of a protein, the rough endoplasmic reticulum (RER) also transports the proteins to the Golgi apparatus where the protein is packaged and processed.

In biology, a carrier protein is a type of protein that transports a specific substance through intracellular compartments, into the extracellular fluid, or across cells as opposed to channel proteins, which is another membrane transport protein, that is less selective in transporting molecules.

Explanation:

Answer:

S phase

Explanation:

In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during the "M phase" (the mitosis phase). During S phase, any problems with DNA replication trigger a ‘'checkpoint" — a cascade of signaling events that put the phase on hold until the problem is resolved. The S phase checkpoint operates like a surveillance camera; we will explore how this camera works on the molecular level. The last 60 years of research in bacterial species (specifically, Escherichia coli) and fungal species (specifically, Saccharomyces cerevisiae), have continually demonstrated that several major processes during DNA replication are evolutionarily conserved from bacteria to higher eukaryotes.

Amongst the array of proteins at the replication fork, DNA polymerases are central to the process of replication. These important enzymes can only add new nucleoside triphosphates onto an existing piece of DNA or RNA; they cannot synthesize DNA de novo (from scratch), for a given template. Another class of proteins fills this functional gap. Unlike DNA polymerases, RNA polymerases can synthesize RNA de novo, as long as a DNA template is available. This particular feature of de novo synthesis is similar to what happens during mRNA transcription.

We have to add s phase in the process of cell cycle at which the enzyme DNA polymerase have the significant role.

Cell cycle is the process of regenerating new cells by dividing the existing cell through several stages namely prophase, telophase, s-phase etc. Both prokaryotes and eukaryotes undergo cell division and produce the identical daughter cells.

Between G1 phase and G2 phase, the cell cycle's S phase (also known as the "synthesis phase") is when DNA replication occurs. [1] Since precise genome duplication is essential for effective cell division, the S-phase mechanisms are strictly regulated and highly conserved.

One nucleotide at a time, DNA polymerase adds nucleotides to the three prime (3')-end of a DNA strand. DNA polymerases are necessary to replicate the cell's DNA during cell division in order for a copy of the original DNA molecule to be transferred to each daughter cell. Genetic information is transmitted in this manner from one generation to the next.
