RoseWind [281]

Answer:

Immunodeficiency disorders prevent your body from fighting infections and diseases. This type of disorder makes it easier for you to catch viruses and bacterial infections. Immunodeficiency disorders are either congenital or acquired. A congenital, or primary, disorder is one you were born with.  whereas Opportunistic infections (OIs) are infections that occur more frequently and are more severe in people with weakened immune systems, including people with HIV. Many OIs are considered AIDS-defining conditions.

Which process occurs in a human muscle when it gets forced to make ATP without oxygen?
antiseptic1488 [7]
<h2>Answer:</h2>

C: Lactic acid fermentation

<h2>Explanation:</h2>

Cellular respiration without oxygen is called anaerobic respiration. ETS (or electron transport chain) reactions happen as the last step of aerobic cellular respiration, therefore it is incorrect.

Lactic acid fermentation is a metabolic process by which glucose and other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. It is an anaerobic fermentation reaction.
