Carbohydrates
________ and lipids, the primary energy- producing nutrients, are repositories of electrons coupled with hydrogen, frequently in the form of C- H bonds.
oxidation of glucose
The ________ in respiration transports electrons to a lower energy state, releasing energy for ATP production.
Photosynthesis
________ produces oxygen as well as organic compounds that are utilized as fuel by eukaryotic mitochondria.
Energy
________ flows into an ecosystem as sunlight and ultimately leaves as heat, while the chemical elements essential to life are recycled, as shown in the image attached.
Fermentation
________ is a catabolic process that involves the partial breakdown of sugars or other organic fuels without the use of oxygen.
Fuels
________ are compounds that can engage in exergonic processes.
puffin
The ________ gets its energy from sand eels and other aquatic creatures, whereas many other animals get theirs from photosynthetic species like plants and algae.
Aerobic respiration
________ is possible in the cells of most eukaryotic and many prokaryotic species.
organic components
The energy contained in food's ________ is ultimately derived from the sun.
Catabolic pathways
________ are metabolic processes that release stored energy by breaking down complex compounds.
summary equation
According to the respiration ________, hydrogen is transported from glucose to oxygen.
major combustion reaction
The ________ that happens at the burner of a gas stove is the oxidation of methane by oxygen.
Energy
________ enters an ecosystem as sunlight and departs as heat; nevertheless, the chemical components required for life are recycled.
oxidation of glucose
The ________ and other compounds in food, however, is the energy-yielding redox activity of most interest to biologists.
aerobic respiration
However, ________ is the most effective catabolic route, in which oxygen is used as a reactant alongside the organic fuel (aerobic is derived from the Greek aer, air, and bios, life)
cellular respiration
The term ________ refers to Including both aerobic and anaerobic processes. However, it originated as a synonym for aerobic respiration because of the relationship of that process to organismal respiration, in which an animal breathes in oxygen.
activation energy
When we provide the ________ by lighting glucose, it burns in the air, producing 686 kcal (2,870 kJ) of heat per mole of glucose (about 180 g).
