Which of the following is the correct sequence of events for muscle contractions?a) motor neuron action potential, meurotransmit
alexandr402 [8]

The answer is; A

When an impulse from the motor neuron reached the neuromuscular junction,  the voltage-dependent calcium channels are activated and the neurotransmitter released from the presynaptic cleft. When the neurotransmitter binds to their receptors on the sarcolemma, the muscle fibers become depolarised; the calcium is released from their vesicles. The Ca2+ ions are important in the power stroke because they bind to troponin. Upon binding calcium, troponin moves tropomyosin away from the myosin-binding sites on actin. Powered by the energy from ATP molecule,  the myosin is able to bind on the actin and slides over the actin filament.

Which molecules are used to produce glucose during the calvin cycle?
Lelechka [254]

Answer:

B. ATP & NADPH

Explanation:

fruits and vegetables are full of energy. Energy in the form of glucose. The energy from sunlight is briefly held in NADPH and ATP, which is needed to drive the formation of sugars such as glucose.

As Melvin Calvin discovered, carbon fixation is the first step of a cycle. The Calvin cycle transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transport chain, excited electrons lose energy to NADPH and ATP. In the Calvin cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose.

How does the protein lactoferrin in breast milk help protect infants against harmful bacteria?
LenKa [72]

Protein lactoferrin is present in human body and it is found in certain body fluids such as saliva, breast milk and urine. The main function of protein lactoferrin is to bind with and transport iron in the body. When an infant absorb iron in breast milk, protein lactoferrin attaches to any of the extra iron that the infant does not absorb and stops it from allowing harmful pathogens such as bacteria to grow in the baby's gastrointestinal tract. Thus, protecting babies from illness and infections.
