The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells
UkoKoshka [18]

The epidermis is a barrier to ultraviolet rays, blocking much of the cancer-causing radiation from reaching the nuclei of cells called keratinocytes.

<h3>What is keratinocytes?</h3>
  • Skin cells, also known as epidermal keratinocytes, are highly specialized epithelial cells created for a very specific purpose: separating the organism from its environment.
  • Keratinocytes, which make up the majority of the epidermis, have a variety of functions that are crucial for skin restoration.
  • They carry out the re-epithelialization process, in which keratinocytes move, multiply, and differentiate in order to reestablish the epidermal barrier.
  • The majority of the epidermis's cells, known as keratinocytes, begin in the basal layer, manufacture keratin, and help to create the epidermal water barrier by producing and secreting lipids.
  • A kind of stratified epithelium known as keratinized stratified squamous epithelium has many layers of squamous cells, or keratinocytes, with the superficial layer of cells being keratinized.
  • The skin's epidermis is made up of this kind of epithelium.

A mutant strain of yeast is able to produce 2 ATP for each glucose molecule digested in the absence of oxygen. What makes this s
Free_Kalibri [48]

Answer:

Explanation:

Normally, under anaerobic condition in yeast, pyruvate produced from glycolysis leads to the production of ethanol as shown below.

pyruvate ⇒ acetaldehyde + NADH ⇒ ethanol + NAD

The pyruvate is converted to acetaldehyde by the enzyme, pyruvate decarboxylase. It should be NOTED that carbon dioxide is released in this step. The acetaldehyde produced in the "first step" is then converted to ethanol by the enzyme alcohol dehydrogenase. It must be noted from the above that the steps are irreversible.

If a mutated strain of yeast is unique because it does not produce alcohol and lactic acid (which is referred to as toxic acid in the question); thus having a high level of pyruvate because of the presence of a novel enzyme.   <u>The function of this novel enzyme will most likely be the conversion of acetaldehyde in the presence of carbondioxide back to pyruvate; thus making that step reversible</u>. This could be a possible explanation for the high level of pyruvate present in the yeast.
