They were found in oceans and hot springs.

Oparin and Haldane's theory proposed that chemicals in Earth's early atmosphere could have formed organic molecules, leading to the origin of life on Earth. They suggested that simple organic molecules could have then combined to form more complex molecules like proteins and nucleic acids.
There were incorporated into organic molecules by plants, they were processed into sugars through photosynthesis, and they are ultimately derived from carbon dioxide.
True. Scientists believe that the first life forms on Earth likely arose from nonliving materials through a process known as abiogenesis. This theory suggests that simple organic molecules gradually evolved into more complex structures that eventually led to the development of life.
They can be chains, rings, or branched structures.
Yes, it is true.
Lipids are diverse molecules that are hydrophobic and soluble in organic solvents. They are important for storing energy, forming cell membranes, and serving as signaling molecules. Examples of lipids include fats, oils, phospholipids, and steroids.
Organic molecules are primarily composed of carbon atoms, often in combination with hydrogen, oxygen, nitrogen, sulfur, and phosphorus. They are the basis of all living organisms and play crucial roles in biological processes, such as metabolism and cellular structure. Common types of organic molecules include carbohydrates, lipids, proteins, and nucleic acids. Their diverse structures enable a wide range of functions within biological systems.
Yes, organic molecules, such as carbohydrates, fats, and proteins, are a source of energy for the body. When broken down through processes like digestion and metabolism, these molecules release energy that is used for various bodily functions. Additionally, organic molecules also provide essential nutrients required for growth, repair, and maintenance of tissues and organs.
No, silk is not considered an organic compound in the traditional sense. It is a natural protein fiber produced by certain animals such as silkworms. Organic compounds typically refer to molecules containing carbon and hydrogen atoms.
True. Photosynthetic bacteria obtain energy by removing electrons from inorganic molecules through a process called photosynthesis. This allows them to generate ATP and ultimately produce organic compounds for their growth and metabolism.
