Why is it important that ions being transported across a cell membrane be shielded from the interior.
In cells the lipid bilayer's core is non polar, ions that are drawn to polar surroundings would be repelled by it.
For cells to continue functioning as they go throughout their life cycle, there must be a tremendous amount of exchange. The integration of living ions and the release of waste materials required for regular operation are both possible during transportation. Simple diffusion in cells and electron transport are the ways by which ions are transported across membranes. Solutes diffuse more easily via channels made of proteins. In order to push ions against the gradient of concentration, active transport needs energy in the forms of ATP conversion, channel proteins, or pumps. These charged (polar) ions do not flow across the membrane because of their charge. They instead travel through ions.

what is the evolutionary benefit to meiosis in reproduction? select only one answer choice. group of answer choices meiosis produces gametes with half the required number of chromosomes that the offspring will need. meiosis produces gametes that are identical to their parent cells. meiosis produces gametes with new combinations of alleles in the chromosomes. meiosis allows for growth and plasticity in multicellular organisms
The evolutionary benefit of meiosis in reproduction is meiosis produces gametes with new combinations of alleles in the chromosomes. Therefore, the correct answer is the third option.
Meiosis is the process of chromosomal reduction that leads to the production of gametes (sex cells) needed for sexual reproduction. It only appears in eukaryotic cells that only plants, animals, and fungis have.
In this process, the double set of chromosomes is reduced into a single set. The single sets combine in sexual reproduction, resulting in double-set offspring. That allows a new combination of alleles in the new gametes while conserving the chromosomal number of the species.

mmediately after the repolarization phase of an action potential, the neuronal membrane is temporarily unable to respond to the stimulation of a second action potential. the brief pause is called the refractory period. what must happen to
The ball domain is released from the channel pore and the channel turns back to closed state after the repolarization phase of an action potential.
The ball domain here describes the ions flowing in and out of the cells in response to the action potentials. A portion of the neuron becomes positively charged when Na+ channels open at the beginning of an action potential, allowing a flood of Na+ ions from outside the cell to enter. This is called depolarization. K+ ions from inside the cell flood out when K+ channels open, making that region of the neuron membrane more negatively charged. This is termed as repolarization. These mechanisms are what alter the cell membrane's voltage.
The brief pause between the opening of these two channels to initiate a second action potential is termed as refractory period. It describes the time it takes for an excitable membrane to reach a resting state after responding to a second stimulus in terms of action potentials.

enteropeptidase deficiency is an inborn error of metabolism that causes malabsorption of protein. the most likely explanation for this malabsorption is that in the absence of enteropeptidase, the only protease zymogen that could be converted to its active form is:
The only protease zymogen that could be converted to its active form in the absence of enteropeptidase is chymotripsinogen.
Trypsinogen is transformed into active trypsin by enteropeptidase, which also activates several pancreatic zymogens in addition to hydrolyzing a few peptide links in specific dietary proteins. Enteropeptidase is a crucial enzyme in the digestion of dietary proteins because of this, and its lack may cause severe protein malabsorption.
Trypsinogen, which is enteropeptidase's main substrate, undergoes a limited amount of proteolysis to release trypsin with catalytic activity. By limited proteolysis, trypsin then acts on the 4 other zymogens to release chymotrypsin, elastase, and carboxypeptidases A and B that are catalytically active.

What's a good format for biology CER/Essay?
The table shows the energy that is stored in three types of organic molecules.
Energy Storage in Humans
Free glucose in blood has 4 kilocalories per gram, 40 kilocalories of energy storage, and a few minutes of life support time. Glycogen has 4 kilocalories per gram, 600 to 1600 kilocalories of energy storage, and 1 day of life support time. Lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time.
What is the best conclusion based on this data?
Blood is a primary location for energy storage.
Fat molecules contain more energy-containing bonds than simple sugars.
A gram of glycogen has twice as much energy as a gram of fat.
The human body stores approximately 1,000 kcal of glucose.
Based on the data shown, the best conclusion would be that fat molecules contain more energy-containing bonds than simple sugars. Option 2.
Drawing conclusions based on dataFrom the available data shown in the illustration, the following can be deduced:
1 gram of free glucose = 4 kilocalories, 40 kilocalories of energy storage, few minutes of life support.1 gram of glycogen = 4 kilocalories, 600 to 1600 kilocalories of energy storage, 1 day life support.1 gram of lipid = 9 kilocalories, 100,000 kilocalories of energy storage, 30 to 40 days of life support.Based on the information extracted, one can see that glucose offers the lowest amount of energy, storage energy, and life support time per gram.
On the other hand, lipid appears to offer the highest energy, storage energy, as well as life support time. Glucogen has values that lie in-between glucose and lipid.
In other words, fats being a type of lipid appears to contain more energy-containing bonds than simple sugar, glucose.
