A mouse cell uses glucose and oxygen, then releases carbon dioxide, water, and usable energy. What process is happening in the cell?
During cellular respiration with oxygen available, what two reactants enter the chemical reactions that release energy from food?
A plant root cell cannot get sunlight but still needs energy. What food molecule can it break down during cellular respiration?
After glucose reacts with oxygen in a muscle cell, what new molecules leave the cell as waste products?
A model shows atoms in glucose and oxygen rearranged into carbon dioxide and water. What else is released during this rearrangement?
In a sealed chamber, oxygen decreases while carbon dioxide increases around crickets. What input are the crickets using for cellular respiration?
A diagram points to mitochondria in an animal cell where glucose and oxygen are used. What happens in the mitochondria?
A poison stops mitochondria from working in a fish cell. What cell function would be affected most directly?
Plant leaf cells have chloroplasts and mitochondria. At night, what process can their mitochondria still perform?
A student says only animal cells do cellular respiration. What evidence would best correct this idea?
A runner's muscle cells need ATP to contract. When oxygen is available, where does much of this ATP come from?
A healing cut grows new skin cells. How does cellular respiration help this growth?
A nerve cell sends signals using energy from ATP. What cellular process helps supply that ATP from food?
A cell is building proteins for growth. Why does breaking down glucose help?
A single-celled organism swims toward food using tiny beating hairs. What does respiration provide for this movement?
Two sealed jars contain moist seeds. Only the jar with living seeds becomes warmer after 2 hours. What does the warmth show?
A respirometer shows a beetle's oxygen level falling over time. What claim does this evidence support?
Students place aquatic snails in dark water with a carbon dioxide indicator. Carbon dioxide rises. What explains the result?
A sealed flask of active yeast gives off bubbles of carbon dioxide as sugar decreases. What does this show about the yeast?
