Question

"Every calorie on this Thanksgiving plate began with sunlight. Plants like sweet potatoes,
carrots, and wheat for the roll used photosynthesis to store sunlight as chemical energy in
sugars and starches. Turkeys and chickens then ate plants and stored that energy as
protein and fat in their bodies. When you eat, your digestive system breaks the meal down
into small pieces, sugars from breads and potatoes, fatty acids from butter and gravy, and
amino acids from turkey and chicken. Those molecules travel in your blood to your cells,
where mitochondria use oxygen to convert their chemical energy into ATP, the energy
currency cells use. ATP powers everything from muscle movement to thinking and body
repair. Some of the energy becomes body tissue, some is used right away, and much of it
is released as heat. Extra energy you don’t need right away is stored as glycogen or as fat.
So, from sunlight to photosynthesis, to animals, to your plate, to ATP in your cells, that’s
how the energy moves and keeps you fueled."​

​

plants convert sunlight to chemical energy and store it as sugars and starch. Animals (and
humans) eat those stored molecules, digestion liberates sugars, fats, and amino acids
that enter aerobic cellular respiration to produce ATP. That ATP fuels movement, thinking,
and repair; some energy becomes biomass, and much is released as heat.










add these two together to make one

Answer 1

Every calorie on your Thanksgiving plate began as sunlight: plants like sweet potatoes, carrots, and the wheat for rolls use photosynthesis to convert sunlight into chemical energy and store it as sugars and starches. Animals (including turkeys and chickens) eat those plants and store that energy as protein and fat in their bodies. When you eat, digestion breaks the meal into small pieces—sugars from breads and potatoes, fatty acids from butter and gravy, and amino acids from turkey and chicken—which enter your bloodstream and travel to cells. In the mitochondria, oxygen is used to convert these molecules into ATP, the cellular energy currency that powers everything from muscle movement and thinking to body repair; some of the energy becomes biomass, some is used immediately, and much is released as heat, while extra energy is stored as glycogen or fat. From sunlight to photosynthesis, to animals, to your plate, to ATP in your cells, that is how energy moves and keeps you fueled.
