To determine:
The process of photosynthesis produces oxygen.
Introduction:
The process by which plants and some kind of bacteria make their food (sugar molecule formation) with the help of carbon dioxide, water, and sunlight called photosynthesis.
Explanation of Solution
There are two stages in the photosynthesis, light reaction, and dark reaction. The main work of these stages is to generate energy for making food to the plants. During the light reaction, one electron from a water molecule is stripped out. The atoms of oxygen from the two water molecules join together and form diatomic oxygen. This diatomic oxygen is released and center of chlorophyll binds new water molecules to produce more diatomic oxygen. For this particular production of the single oxygen molecule, four electrons are used.
During the process of photosynthesis the free oxygen atom joins with the other free oxygen atom to produce oxygen gas.

- One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardHow do i know which way the arrows go?arrow_forward

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly.
