To allow oxygen molecule into the leaf to start photosynthesis, and to allow carbon dioxide out of the leaf after photosynthesis is over.
Answer:
The <u>Kerb’s/ Citric Acid/tricarboxylic acid (TCA) Cycle</u> of aerobic respiration produces FADH and NADH and releases CO2
Explanation:
The Kerb’s Cycle is termed as the cell’s biochemical hub because its main function is to harvest high-energy electrons from carbon fuels.
It is constituted by a series of eight steps of chemical and enzymatic reactions including redox, condensation, hydration, dehydration, decarboxylation etc.
One complete Kerb’s Cycle produces 2 carbon dioxide, 1 GTP, 3 NADH, and 1FADH2 molecules. Each glucose molecule yields two acetyl-CoA molecules and hence each glucose molecule requires two Kerb’s cycle.

Options to this question were not provided. However, it is worthy to note that Mary Ainsworth's theory of mother-infant attachment classifies the relationship that children have with their caregivers as; Secure, Resistant, and Avoidant.

They are also happy when their mother is around.
Generally, these sorts of children are confident and exhibit high self-esteem. So, Austin must have displayed some of these qualities.
