Metabolism and Cellular Respiration

Metabolism

The chemical reactions that occur in a living organism. Obtain energy from food by converting glucose to ATP for use in cellular processes. Convert biomass of food into biological building blocks and excrete metabolic waste.

Anabolic Processes

Build Larger molecules from smaller ones. Require energy.

Photoautotrophs

Use light as an energy source to produce organic compounds.

Chemoautotrophs

Use environmental inorganic compounds as an energy source to produce organic compounds.

Catabolic Processes

Break down larger molecules into smaller ones. Release Energy

Cellular Respiration

Breaks down sugar to generate ATP.

How do we measure metabolic activity?

The amount of oxygen used up for carbon dioxide.

Basal Metabolic Rate

the rate at which an animal consumes oxygen while at rest, with an empty stomach, under normal temperature and moisture conditions.

Maximum metabolic rate

The maximal rate at which oxygen can be transported from the environment to the tissue mitchondria

Aerobic Scope

Capacity of an organism to increase its aerobic rate above maintenance level.

Glucose

A six carbon sugar that stores energy in chemical bonds

Mitchondria

Double membranes organelles, that are descended from bacteria that underwent endosymbiosis, found in ALL eukaryotes.

mitochondrial matrix

The space inside the inner membrane of the mitochondrion

Cristae

Inner membrane folds into structures
