Glucose comes from sugar in food. Oxygen comes from air we breath in. Water comes from water we drink. Carbon dioxide comes from gas we breath out. Enery comes from glucose absorbed in the small intestine.

Why these pure substances come up into mixtures?

Pure substances come up into mixtures because different substances can combine physically without undergoing a chemical reaction. These mixtures can be either homogeneous (uniform composition) or heterogeneous (non-uniform composition) depending on the interactions between the pure substances. Mixing pure substances allows for the creation of new materials with unique properties and characteristics.


Why substances pass in and out of stomata?

Substances pass in and out of stomata through diffusion and active transport. Water and gases like CO2 and O2 enter and exit the stomata to support photosynthesis and respiration in plants. This exchange of substances helps regulate plant water balance and the exchange of gases necessary for plant metabolism.


What substances are removed during respiration?

This is the equation for respiration: glucose + oxygen -> water + carbon dioxide + ENERGY Glucose and oxygen are used to make water, carbon dioxide and energy. So I suppose it could be said that oxygen and glucose are removed


What substances react in aerobic respiration and where do they come from?

Glucose and oxygen are the reactants. In humans glucose comes from digested food, and oxygen is breathed in from the air. In plants, glucose is made in photosynthesis, and oxygen diffuses in from the air.


Which substances are reactants in respiration?

The main reactants in respiration are glucose and oxygen. Glucose is broken down in a series of chemical reactions to produce ATP, while oxygen serves as the final electron acceptor in the electron transport chain to generate energy.
