Answer:ATP, Endergonic, Phosphate group, ATP synthase, Exergonic

Explanation:

1. ATP is the energy currency of the cell. The energy released from the hydrolysis of ATP is use to drive cellular work.

2. ATP are used to drive endergonic reaction. Endergonic reaction are energy requiring hence ATP is hydroxyze to release energy to power endergonic reaction.

3.ATP is formed when a phosphate group is transferred to ADP. Which is an example of endergonic reaction

ADP+Pi+free energy→ATP+H2O.

4. The oxidative phosphorylation of ADP to ATP is catalyze by the enzyme ATP synthase.

5. ATP synthesis is an endergonic reaction in which free energy is needed to phosphorylate ADP to ATP and the reaction is driven by Exergonic reaction.

Maria is a 121-lb endurance athlete who is planning to employ carbohydrate loading before her next race. Which strategy correctl
xz_007 [3.2K]

Answer:

Four to six days prior to the event, Maria should consume 550 g of carbohydrate daily and decrease to 220 to 275 g of carbohydrate daily 1 to 3 days prior to the event.

Explanation:

Carbohydrate loading is for constant  supply of  constant energy as ATPs for the skeletal muscles cells during high intense activity, to reduce fatigue, and increase performance for upmost performance.

The   main objective  is to  sustaining muscle  contraction during intense  exercise  

The practice   involved increase in   intake of high carbohydrate meals  a   few weeks before the commencement of the sporting activities. This is stored  as  muscle glycogen, as well as in the  liver glycogen and brain.  

The physiology involved  the conversion of  muscle glycogen  to glucose -6-phopahate in the liver, and its entry  into Glycolysis, and Krebs’s cycle to generate ATPs.

The use of muscle glycogen during strenuous exercise reduces   blood glucose uptake, and ensured that its level is at a relatively constant value for the body homeostatic conditions, without exogenous carbohydrate intake
