Answer:

The oxygen atoms of CO2 originated from glucose and the oxygen atom of H2O is originated from normal oxygen molecule that act as reactant during the break down of glucose by oxidation.

Explanation:

C6H12O6+6O2=6CO2+6H2O+Energy

In the above reaction glucose is being reduced to generate CO2 .As a result the oxygen of CO2 is originated from glucose.

   The above also deals with the reduction of oxygen to H2O.From that point of view it can be stated that the oxygen atom of H2O originates from molecular oxygen that act as reactant.

Multiple choice, objective response, or MCQ (for Multiple Choice Question) is a form of an objective assessment in which respondents are asked to select only correct answers from the choices offered as a list.

True/False tests contain statements that the student marks as being either true or false. In order to qualify as true, all parts of the statement must be true. In general, true-false tests check your knowledge of facts.

A matching question is two adjacent lists of related words, phrases, pictures, or symbols. Each item in one list is paired with at least one item in the other list. Matching may be considered to be a variant of multiple-choice in which more than one choice is correct.

While opinions may differ, most teachers believe a short answer question typically requires a "short" answer. That doesn't mean an answer lacking depth analysis or information. It simply means an answer that is concise and includes just enough information to accurately and fully answer the question being asked.

Fill in the Blank questions are not opinion-based, which means that learners must be able to use the information they have mastered during the lesson to correctly answer the question. Fill in the Blank questions usually contain a sentence or paragraph featuring a blank space.

Definition of the essay question: an examination question that requires an answer in a sentence, paragraph, or short composition Examples of the essay question in a sentence.

The oral exam (also oral test or viva voce; Rigorosum in German-speaking nations) is a practice in many schools and disciplines in which an examiner poses questions to the student in spoken form. The student has to answer the question in such a way as to demonstrate sufficient knowledge of the subject to pass the exam.

A Checkboxes question lets survey takers select multiple answers from a list of choices. Use this question when you want people to be able to choose more than one answer option in the same question. Jump to...
