Cell Biology Questions

carbons in fatty acids/ carbohydrates are oxidized to _____

when a metabolic fuel is oxidized, its electrons can be transferred to a compound such as... (2 examples)

______ is a mobile electron carrier that shuttles electrons between respiratory complexes in the inner mitochondrial membrane

_____ is a pivotal intermediate in cellular metabolism and serves as a common entry point for various pathways.In aerobic conditions, this intermediate is produced during the breakdown of glucose in the citric acid cycle.what common intermediate does this describe?

_______ is a key intermediate in glycolysis, the process that breaks down glucose to produce energy (ATP) and precursor molecules.It is also a central molecule in the transition between glycolysis and the citric acid cycle (also known as the Krebs cycle) in aerobic conditions.what common intermediate does this describe?

_____ is an intermediate in glycolysis and plays a crucial role in the synthesis of triglycerides (a form of stored fat).During glycolysis, glucose is metabolized to produce it, which can then be used in the synthesis of triglycerides in adipose tissue.what common intermediate does this describe?

t/f: almost all metabolic pathways involve redox chemistry

Liver and muscle tissues polymerize glucose to form ______

after a meal, glucose and amino acids are catabolized to release their stored energy. when these fuel supplies are exhausted, the body mobilizes its storage resources; that is, converts its polysaccharide and triacylglycerol storage molecules to their respective _____ _____.

Proteins are broken down into amino acids by _____ enzymes in the stomach and small intestine.

t/f: most of the body's tissues prefer glucose as their primary metabolic fuel

salivary amylase helps break down what?

virtually all cells take up _____ and immediately catabolize them to produce energy

what are the gastric and pancreatic enzymes that aid in the breakdown of proteins?

____: catalyze the release of fatty acids from triacylglycerols

carbohydrates are broken down into (______) post amylase breakdown

the liver mobilizes glucose by breaking down _____

true/ false: some highly hydrophobic liquids diffuse through the cell membrane, others require transporters

Fats are broken down into fatty acids and glycerol through the action of _____ in the small intestine.

Fats are primarily stored in adipose tissue as _____ for long-term energy storage.
