What relationship are respiration and photosynthesis?

Cellular Respiration and Photosynthesis are the processes of gas exchange by plants and animals.

Difference between Photosynthesis and Cellular Respiration.

The diagrams used in this chapter are only intended to provide a glimpse of the incredible complexity of structure and chemistry that takes place at the microscopic level in organisms, and people can be forgiven for doubting that it is all a miraculous accident. I doubt it, too, as . Prokaryotes do not have organelles such as mitochondria, chloroplasts, and nuclei, but even the simplest cell is a marvel of complexity. If we could shrink ourselves so that we could stand inside an average bacterium, we would be astounded at its complexity, as molecules move here and there, are brought inside the bacterium’s membrane, used to generate energy and build structures, and waste products are ejected from the organism. Cellular division would be an amazing sight.

How do plants and Photosynthesis and Cellular Respiration.

In the earliest days of life on Earth, it had to solve the problems of how to reproduce, how to separate itself from its environment, how to acquire raw materials, and how to make the chemical reactions that it needed. But it was confined to those areas where it could take advantage of briefly available potential energy as . The earliest process of skimming energy from energy gradients to power life is called respiration. That earliest respiration is today called because there was virtually no free oxygen in the atmosphere or ocean in those early days. Respiration was life’s first energy cycle. A biological energy cycle begins by harvesting an energy gradient (usually by a proton crossing a membrane or, in photosynthesis, directly capturing photon energy), and the acquired energy powered chemical reactions. The cycle then proceeds in steps, and the reaction products of each step sequentially use a little more energy from the initial capture until the initial energy has been depleted and the cycle’s molecules are returned to their starting point and ready for a fresh influx of energy to repeat the cycle.

IB Biology: Photosynthesis And Cellular Respiration

The critical feature of earliest life had to be a way to reproduce itself, and is common to all cellular life today. The DNA that exists today was almost certainly not a feature of the first life. The most accepted hypothesis is that . The mechanism today is that DNA makes RNA, and RNA makes proteins. DNA, RNA, proteins, sugars, and fats are the most important molecules in life forms, and very early on, protein “learned” the most important trick of all, which was an energy innovation: facilitate biological reactions. If we think about at the molecular level, it is the energy that crashes molecules into each other, and if they are crashed into each other fast enough and hard enough, the reaction becomes more likely. But that is an incredibly inefficient way to do it. It is like putting a key in a room with a lock in a door and shaking up the room in the hope that the key will insert itself into the lock during one of its collisions with the room’s walls. Proteins make the process far easier, and those proteins are called enzymes.

Cellular Respiration & Photosynthesis

The figure illustrates how closely photosynthesis and respiration are linked. As you can see, thanks to these two life-sustaining processes, plants and animals depend on each other to survive.

A Level | Cellular Respiration | Photosynthesis

Respiration consists of a complicated series of chemical reactions. In the first stage, glucose is oxidized, and the chemical potential energy of its bonds is transferred to the chemical potential bonds of an ATP molecule. The ATP molecule can then be transported throughout the cell where its stored energy is used to complete various tasks within the cell. This process releases carbon dioxide gas and water.
