Chemoreceptors in the body, specifically central chemoreceptors in the brain and peripheral chemoreceptors in the arteries, can detect changes in blood oxygen levels. When oxygen levels drop below a certain threshold, these receptors send signals to the brain to increase respiratory rate and depth to bring in more oxygen.

What is the water activity level in shelf stable chicharrones?

The water level activity in shelf-stable chicharrones is virtually zero. If there was water level activity, the chicharrones would not be shelf stable.


What is HPLC normally used to detect?

HPLC (High Performance Liquid Chromatography) is typically used to detect and quantify compounds in a mixture. It is commonly used in analytical chemistry to separate, identify, and quantify components in complex mixtures such as pharmaceuticals, chemicals, food, and environmental samples.


Why do bacteria not grow in dry flour of powder milk?

Bacteria require water for growth and reproduction. Dry flour and powdered milk have very low water activity levels, which creates an environment where bacteria struggle to extract enough water to thrive. As a result, the lack of available water prevents bacterial growth in these dry powders.


What is the Effect of dilution on enzyme activity?

At a high ion concentration, the ion interfere with the bonds between the side groups of the amino acids making up the enzyme (which is a protein). This causes the enzyme to lose its shape, called denaturation. If the enzyme loses its shape, it can no longer accept and react substrate, so the rate of enzyme activity decreases.


Is there a lot of iodine still available?

There is enough iodine available, as it is an essential mineral used in various industries such as healthcare and food production. However, the availability of iodine can vary depending on supply and demand dynamics in different regions.

How do human muscle cells use lactic acid fermentation to produce energy during intense physical activity?

During intense physical activity, human muscle cells use lactic acid fermentation to produce energy when there is not enough oxygen available. This process converts glucose into lactic acid, releasing energy that can be used by the muscles for short bursts of activity.


When does an activity become anaerobic-?

An activity or exercise is anaerobic if it is intense enough to trigger lactic acid production.
