Most reactions in living things are catalyzed by enzymes, which speed up chemical processes and allow them to occur under the mild conditions present in biological systems. These reactions are also tightly regulated, ensuring that metabolic pathways operate efficiently and in response to the organism's needs. Additionally, many of these reactions involve the transformation of energy, such as in cellular respiration and photosynthesis, to sustain life. Overall, these biochemical reactions are essential for growth, reproduction, and homeostasis.
most things are multicellular. all animals and plants :-)
Living things are characterized by their ability to grow, reproduce, respond to their environment, maintain homeostasis, and adapt to changes. They also require energy to carry out these functions and are composed of cells.
Enzymes that help them react do not work at normal body temperatures
They release energy (they are exothermic).
True. The study of biology encompasses living organisms from the past and present, including fossils and extant species. This broad field examines various aspects of life, from the study of ancient organisms to the exploration of current living systems.
Their chemical balances are maintained by acid-base reactions.
Most reactants in living things are organic molecules, such as carbohydrates, lipids, and proteins. These molecules are involved in various metabolic pathways, energy production, and structural functions within cells. Additionally, many reactants in living organisms are enzymes that catalyze biochemical reactions.
About that of water. This is true of most living things.
No

Yes, it is only true for living things that are small.
Living things are characterized by their ability to grow, reproduce, respond to their environment, maintain homeostasis, and adapt to changes. They also require energy to carry out these functions and are composed of cells.
False.
They do not have the energy needed to react at normal body temperatures.They do not have the energy needed to react at normal body temps.
