The deltoid muscle inserts on the deltoid tuberosity of the humerus and abducts the arm. Imagine a person is holding a dumbbell in their hand and abducting their arm. Identify the fulcrum, the effort and the resistance. Does this joint have a mechanical advantage less than or greater than one? Make a prediction about the power and speed of the joint.

2. sketch the inside of the bean nodule, and describe or label what you observed with the hand lens.

How do high-energy electrons from glycolysis and the krebs cycle contribute to the formation of atp from adp in the electron transport chain? a. high-energy electrons interact with pyruvic acid to create a phosphate bond with adp, forming atp. b. high-energy electrons supply the needed energy to synthesize atp from the lower-energy adp in the electron transport chain. c. high-energy electrons supply a negative charge which causes the citric acid to oxidize, forming a phosphate group to bond with adp. d. high-energy electrons increase the temperature of adp so it easily reacts to form atp.
