A deficiency of which molecule will trigger lactic acid buildup in our muscles? ATP Carbon dioxide Oxygen Water

Oxygen, neccessary for cellular respiration, is the answer. As oxygen becomes scarce, your cells begin to aerobically produce very little ATP, in effect fermenting and producing lactic acid.

Answer:

Oxygen

Explanation:

We as humans are typical eukaryotic organisms and like other eukaryotic organisms, our cells undergo a metabolic process in order to release energy, called RESPIRATION. Cellular respiration can either be aerobic (presence of oxygen) or anaerobic (absence of oxygen).

Our cells undergo aerobic respiration, which involves the breaking down of organic food molecules (glucose) in the presence of oxygen to produce CO2, water and energy (ATP). Aerobic cellular respiration consists of three steps; Glycolysis, Kreb's cycle and Oxidative phosphorylation. Glycolysis occurs without oxygen but the other two processes require oxygen as the terminal electron acceptor.

However, when the cells are in short supply of oxygen (O2), the cells use an alternative method to produce energy. This alternative method is called LACTIC ACID FERMENTATION, which involves the conversion of pyruvate (from glycolysis), in a series of reactions, to lactic acid without oxygen.

In a prolonged oxygen deficiency, the lactic acid builds up or accumulates in the muscle cells to cause MUSCLE PULL.

Answer:

The type of vesicular transport involved in the exporting of protein-based hormones, such as insulin, into the bloodstream is regulated exocytosis.

Explanation:

In general terms, exocytosis is a type of active transport that allows intracellular substances are released to the extracellular space, through of vesicles that fuse with the plasma membrane, which allow the exit of substances from inside the cell.

Regulated exocytosis is the specific vesicular transport for the secretion of substances, such as hormones. For this type of transport to exist, the presence of an extracellular signal is required, which will activate the fusion of the vesicles.

In the case of insulin, the external signal originates with the increase in blood glucose levels, a signal that penetrates the intracellular space and generates an increase in insulin production in the islets of Langerhans (pancreas).

Before insulin secretion occurs, the cell must be depolarized, allowing calcium to enter, which promotes transport by regulated exocytosis of insulin to the extracellular space.

hodyreva [135]

<span>Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by crossing over. The exchange of genetic material between homologous chromosomes is known as crossing over which occurs in meiosis. When homologous chromosomes pair up and exchange different segments of the genetic material. As the result, a new combination of genes will be formed. If there was not crossing over, all genes on a chromosome would be inherited together.</span>

lora16 [44]

Answer:

canaliculi

Explanation:

According to my research on studies by various medical professionals, I can say that based on the information provided within the question the term being mentioned is called the canaliculi. This is a small channel that link together the lacunae and whose main function is routing nutrients to osteocytes and expelling waste products.

Based on this diagram, do you think that organisms of the same order will share a stronger evolutionary relationship than organi

Gelneren [198K]

In taxonomic, the organism is classified based on some similarities. In upper division, the similarities should be more general and in the lower division, the similarities will be more specific. It was mostly based on an organ, example: vertebrate.
An organism with the same phylum could be put in different order.
But the organism with the same order should have the same phylum and class too since order is located below the phylum. That means the organism with the same order should have more similarities than the organism with the same phylum. Those similarities are tightly correlated with the evolutionary relationship.
The image is not really helping since it was showing kingdom division, not the sequence of the taxonomic division.
