Metabolic Road To & From GLUCOSE

The video tutorial covers the metabolic pathways related to glucose and glycogen, including glycogenesis, glycogenolysis, gluconeogenesis, and glycolysis. It explains the meanings of 'genesis' and 'lysis', and how these processes regulate blood glucose levels during fasting and exercise. The role of hormones like glucagon, epinephrine, and insulin in these pathways is also discussed, highlighting how they influence glucose production and storage.

What does the suffix 'genesis' imply in metabolic pathways?

• Storing energy

• Building or making something

• Breaking down molecules

• Transporting molecules

Which condition would likely cause a decrease in blood glucose levels?

• After eating a meal

• During fasting

• After drinking water

• While sleeping

What is the primary organ responsible for gluconeogenesis?

• Pancreas

• Liver

• Heart

• Kidneys

Which pathway involves the conversion of non-carbohydrate molecules into glucose?

• Glycogenolysis

• Glycolysis

• Gluconeogenesis

• Glycogenesis

What triggers glycogenolysis in the body?

• Insulin

• Glucagon and epinephrine

• Thyroid hormones

• Adrenaline

Where is glycogen primarily stored in the body?

• Liver and skeletal muscles

• Heart and brain

• Pancreas and kidneys

• Lungs and stomach

What process is responsible for converting excess glucose into glycogen?

• Glycogenolysis

• Gluconeogenesis

• Glycogenesis

• Glycolysis

Which hormone stimulates glycogenesis?

What is the main purpose of glycolysis?

• To synthesize new glucose
