What steps occur in germination after water uptake?

AveGali [126]

here is the entire process, hope you can answer you question!
Step 1: Imbibition: water fills the seed.
Step 2: The water activates enzymes that begin the plant's growth.Step 3: The seed grows a root to access water underground.
Step 4: The seed grows shoots that grow towards the sun.
Step 5: The shoots grow leaves and begin photmorphogenesis.

Anuta_ua [19.1K]

Feathers are modified as scales. According to the history, birds which have feathers are the descendants of the dinosaurs which have scales.
That's why feathers are categorized as scales in the present record according to studies.

An athlete would like to supplement his diet with the highest concentrate whey protein. What form of whey protein is recommended

AveGali [126]

Answer:

Option B

Explanation:

Complete question -

An athlete would like to supplement his diet with the highest concentrate whey protein. What form of whey protein is recommended?

A. Whey protein powder

B. Whey protein isolate

C. Whey protein concentrate

D. Whey protein with casein

Solution -

Whey protein is taken by people who are intolerant to lactose. Among all the forms of why protein, whey protein isolate consists of 95 percent of protein and hence is the purest form of whey protein. Also the lactose concentration is negligible or absent. This protein also consists of low fat as compared to other forms of whey protein and due to all these features it is a bit costlier than other forms of whey protein

. In which phase of cellular respiration is glucose a substrate?

vodka [1.7K]

Explanation:

During glycolysis, enzymes act on the substrate, glucose. Glycolysis occurs in the cytoplasm; here, 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.
The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
