Front

What happens to glucose when it becomes phosphorylated into glucose 6-phosphate?

Back

It is considered 'hidden' in cells, as phosphorylation traps glucose inside the cell.

Front

In the postabsorptive state, does anabolism exceed catabolism?

Back

No, in the postabsorptive state, catabolism exceeds anabolism.

Front

Is glucose oxidized or reduced during metabolic reactions?

Back

Glucose is oxidized during metabolic reactions.

Front

What are the folds of the stomach called when it is empty?

Back

The folds of the stomach are called rugae when it is empty.

Front

What is the final step of chemical digestion?

Back

The final step of chemical digestion occurs through enzymatic action, but it does not involve the synthesis of vitamins.

Front

Define anabolism.

Back

Anabolism is the metabolic process that builds larger molecules from smaller ones, often requiring energy.

Front

Define catabolism.

Back

Catabolism is the metabolic process that breaks down larger molecules into smaller ones, releasing energy.

Front

What is the role of enzymes in digestion?

Back

Enzymes facilitate the breakdown of food into smaller, absorbable components.

Front

What is the significance of glucose 6-phosphate in metabolism?

Back

Glucose 6-phosphate is a key intermediate in glucose metabolism and is involved in energy production.

Front

What is the difference between oxidation and reduction in metabolic reactions?

Back

Oxidation involves the loss of electrons, while reduction involves the gain of electrons.
