When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis . Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy and oxidation of fat for energy .

Overall, when carbohydrate intake is excessive, lipogenesis

Increase or decrease

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis  decreases.

The process of conversation of stored glycogen in the liver and muscles  to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)

Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases and oxidation of fat for energy ___decreases .

Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose  move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.

Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO

Explanation:

im not in connections yet but i might can you some questions. what grade are you in?

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
