A glucose molecule is completely broken down to carbon dioxide and water in glycolysis and the citric acid cycle. True or False
lutik1710 [3]

Answer:

True

Explanation:

A glucose molecule enters glycolysis in the cytoplasm of the cell. The glycolytic reactions break down one molecule of glucose into two molecules of pyruvate. Each of the pyruvate molecules is then decarboxylated and is oxidized into acetyl CoA. Acetyl CoA enters Kreb's cycle. Acetyl CoA is completely broken down into CO2 and H2O in Kreb's cycle. In this way, glycolysis and Kreb's cycle break down the glucose molecule into CO2 and H2O in a stepwise manner.

Consider the following food chain: garden plants are eaten by snails, which are eaten by birds, which are eaten by the household
SIZIF [17.4K]
The garden plants and snails stay balanced as they are still being eaten. However, if the cat is removed, the birds will overpopulate and then the snail would be eaten and decrease faster which gives garden plants an increase in population due to the decrease in snails. Hope this helps!

What type of molecule can easily diffuse through the plasma membrane without any help? Why?
babunello [35]
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
