Even though plants carry on photosynthesis, plant cells still use their mitochondria for oxidation of pyruvate. when and where will this occur? a. in photosynthesizing cells in dark periods and in other tissues all the time b. in cells that are storing glucose only c. in photosynthetic cells in the light, while photosynthesis occurs concurrently d. in photosynthesizing cells in the light and in other tissues in the dark e. in non-photosynthesizing cells only

The correct answer is: a. in photosynthesizing cells in dark periods and in other tissues all the time

Cellular respiration is a process, more precisely set of metabolic reactions used to convert biochemical energy from nutrients into energy (ATP). One of the steps in cellular respiration is oxidation of pyruvate that occurs in mitochondria of all cells.

During the dark period only respiration takes place (oxygen is used, carbon dioxide is reeased). But, during daytime when the light is bright, photosynthesis in photosynthesizing cells produces oxygen and glucose faster than respiration consumes it.
