Bumek [7]

Answer:

A. Cellular respiration

C. Photosynthesis

Explanation:

There are two main processes occurs in the carbon cycle i.e. cellular respiration and photosynthesis. Plants absorb carbondioxide gas from the atmosphere through small openings called stomata. The carbondioxide enters the leaves and combine with water produces glucose and oxygen. Glucose is stored in different parts of plant whereas some oxygen is used by the plant and the remaining oxygen is releases in the atmosphere while on the other hand, in cellular respiration, glucose is broken down to produce energy in the form of ATP, carbondioxide gas and water.

In which process is lactic acid formed when there is not enough oxygen present for cellular respiration to take place?
Olenka [21]
Anaerobic respiration.
<span>Anaerobic respiration is a type of cellular respiration BUT does not use oxygen (O2). It is used when there is not enough O2 for aerobic respiration.
</span><span>It can be summarised by the equation: glucose → lactic acid (+ energy released). However, it releases less energy than aerobic repspiration due to a lack of oxygen resulting in an INCOMPLETE breakdown of glucose.
