Front

What triggers the release of glucagon?

Back

Low cellular ATP concentration triggers the release of glucagon, which causes the breakdown of stored glycogen into glucose.

Front

What is an example of a hydrogen bond?

Back

The attraction between a hydrogen of one water molecule and the oxygen of another water molecule is an example of a hydrogen bond.

Front

What are the products of the process that yields monosaccharides?

Back

The products of the process are monosaccharides.

Front

What does a saturated triacylglycerol contain?

Back

A saturated triacylglycerol contains the maximum number of hydrogen atoms in the fatty acid chain.

Front

Which letter corresponds to a monosaccharide in a given picture?

Back

Letter A corresponds to a monosaccharide.

Front

Define glucagon.

Back

Glucagon is a hormone produced by the pancreas that raises blood glucose levels by promoting the breakdown of glycogen.

Front

What is a hydrogen bond?

Back

A hydrogen bond is a weak attraction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Front

What are monosaccharides?

Back

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose.

Front

What is the structure of a saturated fatty acid?

Back

A saturated fatty acid has no double bonds between carbon atoms, allowing for the maximum number of hydrogen atoms.

Front

What is a glycosidic linkage?

Back

A glycosidic linkage is a type of covalent bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate.
